This is one of the best Air BnBs I've stayed in. Very clean, very private, Celia was a fantastic host. I was in town to run the marathon so I had to make the 25-minute trip into the city a bunch of times--very easy and no train transfers.
The room was actually a little more spacious than expected, and has separate sitting and sleeping areas. Also, the great, new bathroom is attached!
I'll stay again in a heartbeat if I'm back in Boston.
