Staying in Katherina's house is like staying in a five star boutique hotel with helpful host ! It's so clean and beautiful, with flowers and crystal lamp and candles; also the service is wonderful too. Katherina put fruits , candies , juice and cookies to welcome the guests. She also provides very nice quality white towels of different sizes in the room. On top of that, Katherina is a wonderful host. She is so helpful and acoomodatinf, letting me checking in and out on time but place luggages for my convenience. She is also very fast in replying my messages (which a lot of hosts DON'T do and creep guests out!). The area is residential area which you can avoid tourists, but also has a lot of very nice bars and restaurants. The traffic is so convenient as well. It's an amazing experience staying in Katherina's place- I would stay here again if I come visit Berlin again !
