We have received very warm welcome despite our late arrival due to fly problem with easyjet. Kelly gave us many tips and information about Berlin : places to go and visit, transportation and restaurants. This flat was very clean and convenient. Location is really great and close to buses and subway.
Few advices to improve the overall comfort of the flat : hot water and shower could be more convenient. The all flat seems to be a commercial for ikea furniture. Bed sheets could be improved.
Anyway, a place to stay in Berlin.
