Sami's house is perfect if you're looking to discover Boston with a limited budget. It's located about half an hour from the city center and reachable by subway followed by a short bus drive, both are very frequent (minutes apart).
The room is small but more then enough, with a strong bunkbed and the bathroom just next to it. Sami had to leave for a couple of days but still took the time to text us is to see if we were fine. Great experience!
