Vivien’s apartment is a great sized 2 bedroom apartment and is great value for money. It is excellently located with many restaurants ands shops close by and also easy access to central Berlin by tram.
Vivien was extremely helpful when my travel plans were disrupted and when I accidentally left my passport upon leaving. Although she did not have a spare key in Berlin, she got back the next day as quickly as she could and was very quick with communication.
Would definitely recommend for staying in Berlin.
