The room is very nice, it has a good size and the entire apartment meets its purpose just fine. Of course, with five rooms, sometimes with two people per room, it can get a bit tricky if everyone decides to take a shower at once. Still, the stays seem to be rather short and that helps with everyone accepting that fact, because it's not for long anyway.
Most of all, however, I'd like to tone down what some people wrote in the reviews for this room: it is not that loud. Of course you hear cars pass by, and the occasional guest closing a door, but if someone is bothered by that, maybe they should reconsider their options for accommodation. I slept like a baby.
