First of all, the apartment has a very good location. Being close to Hollywood Blvd, Sunset Blvd & Highland Ave is very convenient and nearest park (Runyon Canyon) is beautiful.
As for the apartment itself, it was clean, not a big one, but was sufficient for us as we were a group three friends (2+1) concerned about a place to rest between trips to various attractions. There weren't any problems with contacting our host or organizing a futon for our friend (which he mentioned was very comfortable :) ) There is a nice bonus to the studio - fire escape next to your window with a really nice view of the Hollywood Hills. The building also has a nice little garden which was always empty and we felt like the only people who used it. Only con that comes to mind was really slow elevator.
