My girlfriend and I spent one night at Mary's privete room. The room is pretty much what is shown on pictures, the bed is comfortable, the AC was very useful in september. The street is very noisy and full of people at weekends: there's a nightclub near the building. The noise can be an issue if you need complete silece to sleep. During the day we used parkmeters (its expensive to park even on the street and the parkmeters have a 1 hour or 2 houra limit), because the parking lots don't allow you to get in and out. However there's a lot of parking lots in the area (some of them closing at 4 AM on saturday). The building is very close to the main atractions of Hollywood and some nightclubs and bars.
The shared bathroom is very clean! The bedroom had enough space for all our luggage. The building is very clean and organized.
