We were warmly welcomed by Oliver. He took the time to show us around the house, and gave many recommendations on which places to visit and where to find supermarkets and public transport.
The house is nicely located in a quiet area, but still very close to all facilities and the centre. It is spacious, and located in a courtyard. The kitchen is well equiped, although the fridge was a bit too small for a group of 9 (it only fits daily shoppings), and we missed a chopping board. The showers were really nice!
If you go to Berlin with a group, we would certainly recommend it!
