Katrin and her family are great hosts that will make you feel immediately welcome and part of their daily lives. Her two children are lively and full of interests, and at the same time so well-behaved that it looks like they are used to having guests since forever. Katrin is always available and resourceful and managed to find the time to prepare breakfast every day. The guest room is at the third floor of their 3-stories house in a quiet neighbourhood at a stone's throw from the Freie Universität. You will have the room for yourself, plus a living room with a kitchenette. The area is well served with several buses and a U-Bahn stop a few minutes away. I can't recommend these hosts enough: we went to the dress rehearsal of the Philarmonie's choir together, I got to meet some very special friend of them and have had some nice chat with Katrin and the children. At the same time, Katrin has always been very tactful and respectful, so you will free to arrange your stay as you prefer. Looking forward to come back to Berlin and visit them again!
