This is a great apartment, it looks exactly like on the photos and is very beautiful and clean. The location is perfect, right accross the street is the u-bahn/s-bahn stop Frankfurter Allee which takes you directly to basically all the nice places in Berlin. I love Prenzlauerberg, you have to find out where to go but it has a few real nice coffee bars and breakfast places.
Frank was a great host, very friendly and helpful. We gave him a call when we arrived and he was there within five minutes. We will definitly come back here!
