Heike and Miguel have been great hosts. The flat was amazingly clean and tidy, and the beds (including the wall bed) were very comfortable. The area is quiet enough to get a good night sleep and within very easy access to get into town. There are some lovely coffee shops, restaurants and a supermarket within a few minutes walk, as well as a fantastic book shop with books from all languages. Heike and Miguel were very accommodating and we had a great time in Berlin.
