Sublet or Airbnb for a Boston internship, co-op or semester?

An Airbnb monthly stay can be quicker to book and includes Airbnb's help if a listing falls through. A sublet means signing a sublease with the student who rents the place, with their landlord's approval, and paying their rent directly. Massachusetts generally taxes short-term stays of 31 nights or less, so Student Spots sets a 32-day minimum.

This guide is for students who need a place in Boston for a few months: a summer internship, a Northeastern co-op, a semester. Student Spots is a sublet marketplace, so we have a side in this. We've tried to be fair about what Airbnb does well, and the sources at the end are mostly Airbnb's own Help Center pages.

Sublet vs Airbnb at a glance

Is it cheaper to sublet or Airbnb for a summer internship in Boston?

It depends on the place, so compare the total you would pay for your dates. What goes into each total is different.

On Airbnb, the price you see includes Airbnb's service fee. As of November 2026, Airbnb is moving home hosts to a single fee that the host pays, 15.5% for most hosts. Hosts still on the older split fee usually pay 3%, and their guests pay a fee of 14.1% to 16.5%. Either way, US guests see the total with fees before taxes, so the number on the listing is close to what you pay. For a stay of 31 nights or less, occupancy taxes go on top. The next section covers those.

On a sublet, the cost is usually just the rent. On Student Spots, renters pay no Student Spots fees. Sublease listers pay a listing fee ($50 per opening), and any agreement fee comes out of their payout, not your rent. Pricing has the full breakdown.

A few things to check on either side before you compare:

• Whether utilities and internet are included, or split with roommates.
• Whether the room is furnished, and what is left in the kitchen.
• Whether there is a security deposit. Airbnb says most of its hosts can't charge one. In Massachusetts, a landlord's deposit is generally capped at one month's rent (M.G.L. c. 186, §15B).
• How close it is to work or campus, and the T line you would use.

What taxes apply to stays of 31 nights or less in Massachusetts?

Massachusetts charges a room occupancy excise on short-term rentals, including ones booked through Airbnb. The rule is in 830 CMR 64G.1.1, and it covers a stay of 31 consecutive days or less. In Boston, as of November 2026, that means:

• a 5.7% state excise,
• a 6.5% local excise, and
• a 2.75% convention center financing fee.

That comes to about 15%. Some short-term rentals in Boston also pay a 3% community impact fee, for example professionally managed units. Airbnb collects and sends these taxes on bookings made through it, so they show up at checkout.

The line matters. When a short-term rental stay runs longer than 31 consecutive days, the regulation says no excise applies to any part of it, including the first 31 days. Hotels, bed and breakfasts and licensed lodging houses follow a different, 90-day rule.

Why do Student Spots listings have a 32-day minimum?

Student Spots listings have a 32-day minimum. That keeps a stay past the 31-day line in the state's room occupancy excise, and past the 28-night line in Boston's short-term rental rules. A stay on Student Spots is meant to be a sublease of someone's home, not a short-term rental.

It also matches how students move. A summer internship, a co-op and a semester usually run longer than a month. If you only need a place for two or three weeks, an Airbnb or a hotel is likely the better fit.

The minimum is a product rule, not a tax ruling. A lister's own situation, such as the type of building, can bring other rules into play.

Can a Boston renter put their apartment on Airbnb?

Generally not for short stays. Boston's short-term rental ordinance covers stays of fewer than 28 consecutive nights. Only the owner of a unit can register it, and only as their own home or a unit in a two- or three-family building they live in. A tenant generally cannot register their rented apartment. Boston also requires each listing to show its city registration number. Airbnb's own Boston page also tells hosts to register with the city.

For you as a guest, that gives you a simple check. A Boston listing for fewer than 28 nights should show a registration number. If it doesn't, ask why.

Stays of 28 nights or more fall outside the ordinance, but the host's lease still applies. Airbnb's Terms of Service note that some leases restrict subletting and longer stays, and Airbnb tells hosts to check with their landlord. If a tenant hosts against their lease, the landlord can object, and your stay can get caught in it.

Do you need your landlord's approval to sublet in Massachusetts?

It depends on the lease. MassLegalHelp, a legal aid site, explains that a tenant with a lease that says nothing about subletting can generally sublet. Many leases do say something: they require the landlord's written consent. Subletting without it can put the original tenant at risk of eviction, and the original tenant stays responsible for the rent.

On Student Spots, a sublease publishes only after the lister confirms their landlord's written approval. They also upload their master lease before they accept a sublessee. Student Spots does not contact the landlord or check the approval, so it is fair to ask the lister to show it to you. Student Spots also does not run background or credit checks on anyone. Students confirm a .edu email or upload a student ID to message, apply or list.

The Massachusetts sublease guide goes deeper on the law.

What do you sign, and how do you pay?

On Airbnb, you usually sign no lease. Airbnb's Terms of Service describe a booking as a limited license to use the place. The first month is charged when you book, and Airbnb holds it until 24 hours after check-in. Each later month is charged 10 days before it starts. Airbnb's own host guidance notes that, in many places, a guest who stays around 30 days or more may gain rights as a tenant.

On Student Spots, you and the sublessor sign a written sublease in DocuSign. The first month's rent is paid on Student Spots by card through Stripe, which activates the sublease. Later months are paid directly to the sublessor or the landlord. When a payout hold applies, the first month waits until 24 hours after move-in before it goes to the sublessor, and your agreement page says so before you pay. Before you apply, you can video call the lister or ask for a live video tour in the app. How it works walks through each step.

What happens if your plans change?

Internships move and co-op offers fall through, so read the cancellation terms before you commit.

Airbnb uses a long-term cancellation policy for stays of 28 nights or more. The host picks one of two:

• Firm: a full refund if you cancel at least 30 days before check-in. After that, the host is paid for the nights you stayed plus the next 30 nights.
• Strict: a full refund only if you cancel within 48 hours of booking and at least 28 days before check-in. After that, the host is paid for the nights you stayed plus the next 30 nights.

Airbnb's guest page adds that if you cancel after the stay starts, the following month is nonrefundable. Check the exact policy on your own reservation.

On Student Spots, either side can cancel a signed sublease before the first month's rent is paid, with no penalty. No rent has been charged at that point. After the first payment, the sublease you signed and Massachusetts law decide what happens. So read the sublease's terms on ending early before you sign.

When is an Airbnb monthly stay the better pick?

Airbnb does several things well, and sometimes it is the right call:

• Short or last-minute stays. For fewer than 32 days, or a few weeks before your lease starts, a sublet on Student Spots won't fit.
• AirCover for guests. If the host cancels, you can't get in, or the place is significantly different from the listing, Airbnb tries to rebook you or refunds you. You report it within 72 hours of finding the problem.
• Support around the clock by phone, email or chat.
• Reviews tied to real stays. Airbnb reviews have to relate to an actual reservation, and neither side's review posts until both have reviewed or 14 days pass.

A sublet tends to suit a longer stay where you want to live like a resident: a room in a shared apartment, often with student roommates, a written sublease and rent paid to a person rather than a platform.

Sublet or Airbnb for a Northeastern co-op?

Northeastern co-ops usually run four or six months, so a co-op is well past the 32-day minimum. Over that length, a sublet is often the simpler fit: one sublease for the whole co-op, and a stay past the 31-day line in the state's occupancy excise, which generally means it does not apply. Airbnb can still work for the first few weeks while you look for something closer to your employer.

Co-op cycles also free up rooms. Some students leaving Boston for a co-op sublet their place for those months. The guide to off-campus housing near Northeastern has the co-op dates, the neighborhoods and how subletting works there. Leaving Boston yourself? Sublease your place covers the steps.
