400 Columbus was in an excellent location, within walking distance of public transportation, many restaurants, and grocery stores. The studio apartment was very small, which wasn’t too much of an issue. It could get noisy at night, but that is to be expected with staying in downtown Boston. However, there was some torn carpet with sharp pieces exposed underneath, which was a concern. Also, the drain in the shower was very slow, causing an accumulation of several inches of water during showers. Check in and check out were simple, hassle-free, and communicated clearly. I would stay here again if the aforementioned issues were repaired.
