The set up is much like a dorm. The rooms are located off a main hallway with the kitchen down the hall. The bathroom opens into the kitchen which is a little awkward but functional.
The street noise is very apparent since the room is on the front of the building where there is a main road of traffic. You can hear most every one that passes by, as well as all the emergency vehicle traffic. I'm a pretty heavy sleeper so it wasn't a big issue one's I fell asleep, but if you're a light sleeper it may be an issue.
