Stay at Heidi's apartment was a great experience. The flat corresponds to the description provided, small but confortable and completely suitable for a couple. There isn't a real kitchen but there are a small fridge, a microwave and a cattle: more than enough for our needs. The location is the best: you can reach the city centre by foot, but a metro station is few step far from the flat. Our host Heidi was very kind, we'll recommend her and the apartment for a pleasent holiday in berlin.
