The flat is located in the lovely Richardkiez in Neukölln. You will find everything you need here. It would be nice if you stayed for at least 10 days. If you write in advance and want to stay for a longer period its possible to negotiate the price.
We live here as a family so it would obviously be nice if nothing breaks and you don't try to scare the neighbors away with extremely loud music, Partys or anything alike. But we don't expect that from anybody so i guess there won't be any problems.
