The room is easy to get to with metro and very close to the airport. Everything is easy to find, self check-in works well. The rooms have everything you need, there is a common kitchen and bathroom. WIFI worked fine. From the cozy room I could hear the highway in the background, but it is not very loud. Less so from the "Swan room", which is also bigger. The "cozy room" is really quite small - and as advertised - cozy. (this review is on both rooms, since I was renting both rooms together with a friend.)
Shelly explained where to find everything in Boston, was very quick in answering mesages and was really lovely in messages and in person.
