I have been staying at Katrins wonderful place for over a month, and I have nothing but positive things to say. I booked the room in jan, and our communication has been delightful all the way through. The room is perfect, with a comfy bed, a place to put your clothes etc, and it has everything you need. There is a large kitchen for you to cook and a nice bathroom as well. The room is good for both short and longer stays. Also there are three cute cats who likes to cuddle. The location is near everything: supermarkets, bars, restaurants, parks, S- + U-bahn... You name it.
Katrin is such a nice and cool person, and I can only recommend others to book this room in the future, if you are visiting Berlin.
Staying here is an experience you'll never forget!
