Great flat, roomy, clean, great location, Birgit was lovely and very responsive. Unfortunately though one of the neighbours called the police on us for playing music from a small portable speaker, so not very loud. She explained that there were people staying in the flat the week before who were very loud and warned us the police were coming, but didn't ask us to turn the music off before she called them. Naturally we turned the music off and when the police came we were getting ready to go out, nonetheless they were very rude and threatened to confiscate our keys and evict us from the flat as it is a residential building and we were not from Berlin.
