Positive things first: the flat is rather nice, the location too, very close to back bay station (a bit more than 5 walk), a bit less to the green line (around 10mn). On the down side: this is more a hotel room than a real flat. The kitchen is barely usable, I had almost no cutlery, and basic things were not provided: I had one tiny trash bag for the whole week, no salt, oil, pepper, etc. If you plan to stay there for the night, this is fine. But if you plan to stay for the week, I'd look for something else. Also I underestimated the noise problem reported by other guests: you hear your neighbours talking as if they were in your kitchen. At two occasions, I had really noisy neighbours and that was really unpleasant.
