Great location - centrally located in Boston's Back Bay, tons of food options and tourist attractions. Check-in is easy, all electronic.
A few things to note, the listing is in a building made up of other shared lodging, which wasn't apparent to us when we booked this. So in a way, it's not that different than a hotel. That may or may not be an issue. The kitchen appliances--microwave, fridge, and toaster--worked well.
Similarly, our room is joined to another with a firedoor, which is not soundproof, so we heard our neighbors when they were in.
Lastly, the bed is a bit short. For us, and anyone over 5'10"-5'11", your feet dangles off of the bed when sleeping. We also found that, in winter, the single comforter may not be enough for warmth, as there's a little bit of draft. We asked for another comforter but never heard back, perhaps as it was around Xmas.
The location is very convenient, which is a huge plus. And when we needed to extend our stay, management was fast in updating. Especially if you're a single traveler, it's a great option to a hotel and priced more competitively.
