This was a great spot for a solo traveler in Boston. The Back Bay location gave easy access to a lot of great activities and the apartment was wonderful and clean. It was exactly what I needed. Check-in was a breeze and the main amenity I cared about (wifi) was fast and stable. The bed was really comfortable... Best bed I've slept in while traveling in a long time, and I have been on the road a lot lately. I would absolutely stay here again.
Only word of caution: if you are a light sleeper, Newbury Street can be loud at night, on the weekends in particular. It wouldn't keep me from renting again myself, but if you absolutely need quiet, I might look somewhere else.
