The more important thing is to know that the flat is on an extremely noisy street and sleep is simply not an option until 2/3am in the morning. People drink and sing on the street. The second critical thing to know is that all 4 beds in the flat produce an extremely loud sound every time you move in bed. Most doors can't be shut either, including the bathroom. All else is fine but if you want to get some sleep and not hear every movement of other people in the house, this is not your place.
