We had a lovely few days staying in Konstantin's apartment and felt very at home there. The flat is spacious and airy with all the essentials. The bed was really comfortable. This was an ideal base for exploring the city as it has convenient transport links (U-bahn and S-bahn stations are walkable from the flat.) Lots of little cafes, bars and restaurants to enjoy in the lively Neukölln area. Konstantin was a helpful and friendly host and was very flexible. Communication was easy and we were able to contact him when needed. Thanks so much for having us!
