The hosts made me feel welcome but did not intrude. They live in the same building so I knew they were there if I needed them and I did ask them to do something for me which was done without a problem. The apartment was just as described and I really enjoyed staying there. After 11 days I felt like a local! Prenzlauer Berg is a terrific area, very quiet and safe with lots of lovely cafes and restaurants and cute little shops. Highly recommended.
