I loved this apartment! Ivo's friend Anna met me when I arrived, and she was flexible, answered me fast on the phone and behaved nicely. The apartment is in a backyard in a very quiet street and I had a really good sleep there every night. The bed was comfortable, and since the apartment is on the ground floor, it wasn't getting too hot though it was the end of July. The apartment is close to public transport and the very nice neighborhood of Prenzlauerberg, with a lot of cosy cafees, restaurants, bars and shops. I recommend hiring a bike instead of taking the u-/s-bahn, because you can reach almost everything by bike from here. I would definitely go back!
