First of all, the air conditioning was absolutely fabulous. If this is as important to you as it is to me, then you've found your place. The location was also perfect because we were taking our kid to Emerson and it's just a block away. In general, it's a great area to stay with a T stop kitty corner across the street, Boston Common right there, and lots of great restaurants of all kinds. Also many theaters within walking distance.
The whole place was super clean and check-in/out were easy and quick. We didn't cook, but the kitchen was well equipped if we'd wanted to. I know some others have said that they did not have enough linens when they had 3 or more in their group but we had plenty and the couch was made up with a sheet already when we arrived. It could be a bit noisy in the night but not so much that it disturbed our sleep. This will definitely be our go-to lodgings for subsequent visits.
