one of the hotels frequently used in this way was the former howard johnson's hotel at 575 commonwealth avenue, next to the questrom school of business' rafik hariri building. in 2001, the university closed the hotel (which it owned) and converted the building into a full-time dormitory, now known as 575 commonwealth avenue. rooms are commonly divided into triples, although there are a few doubles and singles. every room comes with its own bathroom and air conditioning, a luxury not present in most rooms on campus. this 8-story building, not including the basement, includes the first floor lobby, 6 floors for bedroom dorms, and an eight floor study area. the first floor lobby also has two lounge areas, where students can choose to study or hang out by playing pool or watching tv. students lovingly refer to it as either 575 or the hojo.
