I wasn't sure how I'd like the idea of renting a room in someone's house but this place is set up great. I was there for 3 nights and had plenty of privacy (my preferred method of hospitality). No problems checking in or getting into my locked room. Everything was sparkling clean and well appointed. The room was more spacious than it appeared online. I never had any competition for the restroom. I didn't even run into the other guests until my last day.
I don't know the city well and wasn't sure about the neighborhood but I was pleasantly surprised. I felt perfectly safe making the short walk to the train all by myself even after dark. The train connected me to every part of the city and I even used it to go to Braintree and Woburn far outside the city. This option made my last-minute trip much more affordable and comfortable than I expected.
