My family enjoyed our stay at this apartment. It was clean and spacious for an apartment in the heart of downtown Boston. Brian was quick to respond when we made him aware of an issue.
As others have noted, the location itself does have pros and cons. If you are looking for a nice place in a lively area in the heart of Boston, this fits the bill. If you are sensitive to noise, you should be aware that the subway red line runs underneath this building and the apartment overlooks a street busy with pedestrian traffic.
