I was in Cambridge to study at Houghton Library, so I was looking for a place that had a kitchen, was comfortable, and was close to Harvard. This apartment has all of those qualities. I also wanted a place to stay that wasn't a room in someone's home, wasn't a bed and breakfast, and wasn't a hotel.
The apartment is on the third floor of a building with about five or six floors. In terms of layout, there is a small kitchen area, a small utility room (with washer/dryer combo), a small bathroom, and three larger rooms: sitting room, office, and bedroom. Windows run along the length of these rooms, so the apartment is light. As other reviewers have noted, it is uncluttered. These qualities worked for me. I was there alone and "on business" essentially.
If you're looking for a place that is suited for more than one person, this may or may not be the best place for you. There's a little table to eat at, but it's not really a dining table. There's a futon to relax on, but the television is across the room; so the layout maybe is not particularly conducive to a couple cooking a meal, having dinner, and relaxing in the apartment itself.
That said, Cambridge has a ton of things to do and places to go, so I'm not sure that many people are looking for what I just described. If you want a place that is central--a short walk to Harvard Square, with easy access to bus lines and subway, plenty of restaurants within walking distance--quiet, clean, and comfortable, then this is a great choice.
