Ann was a great hostess. She replies very quickly and she is really nice. The room in this flat is was so clean and so comfy. It feels like a hotel with your own private bathroom within the room. A view of the backyard with trees is also very nice. I live in Berlin and I can also say the location of this flat is perfect. Right in front of Volkspark Friedrichshain. The flat also has a small kitchen equipped with a dishwasher and even a washing machine for your clothes.
Highly recommend it!
