The location was super convenient - near the T, a grocery store, and downtown. However, note that the unit is in downtown crossing, not the financial district as advertised. It's a 2 min walk from the DTX station.
Boston's a major city and so it's unfortunate but expected that there are many struggling people experiencing homelessness, but there tended to be more near the unit than in more touristy areas like the Waterfront, downtown, or Back Bay.
The area also gets really quiet and a little sketchy late at night so be wary if you are traveling alone.
Keyless entry is seamless. The unit itself was pretty clean. Nice, glass shower, and the unit has great AC!
There is laundry in the building for $2.50 each cycle.
Overall, the place is solid and has all the basics, but don't expect anything extra - you'll have to go out and buy all cooking supplies (including salt/pepper and oil) and even hand soap.
