Wonderful and cozy place! The flat is 2 minutes away from a S-Bahn station and 7 minutes walking from an U-bahn station so getting around Berlin is no problem. Wilmersdorf is quiet and peaceful but just a couple of station stops away from Mitte, Xberg, Prenzlauerberg, Neukoeln etc.
Petra is a very warm and lovely host who makes you feel at home right away. She's a great conversationalist and very well traveled with a lot of helpful advice for getting around Berlin. Truly one of the best AirBnB experiences I've ever had!
