Had a wonderful time at Valentina's place. The apartment is neat, tidy and comes with a lot of facilities. For two people, it is absolutely perfect. The location is outstanding too, with numerous restaurants, bars, cafés and supermarkets nearby, and really well connected by public transport as well.
Valentina was very responsive and aided us in checking in on the first night. She also was kind and understanding, and generously allowed us a late checkout aa well. Everything was top-notch, and I highly recommend this place to anyone visiting Berlin.
