Our stay at Mary's was really nice. Getting the key was really easy and uncomplicated. The room was actually bigger then we expected, there was enough space for the three of us and our luggage.
As Mary mentioned the place isn't calm, which is not really a suprise, because it's near to the Hollywood Boulevard. If you forget your earplugs, there are some in the room, therefore sleeping shouldn't be a problem.
The bathroom was clean and nice.
