Lovely, spacious room in a safe neighbourhood. The photos do not do the room justice - it has so much space and is light and airy. I was there over the course of three seasons and it was cool when needed, but warm in the winter. Great amount of storage space. There is space to park a car out front; although the bus goes straight to Harvard and Longwood Medical, so great if you need to access those places.
In addition, Bo and his family are extremely welcoming and very responsive. They were always kind to me and very considerate.
Things to be aware of - sound does travel, so bring ear plugs if you're a light sleeper. The occupants of the other three rooms rotate round so your flatmates may change; although I had difficulties with one, I mostly got along really well with the others.
I really enjoyed my stay and would recommend to all.
