Frank's apartment is just perfect. It has everything you might need. The bed is super comfortable, in fact I slept better than at home. The small street in front of the house is lined with trees and is very quiet.
The location, in the middle of Prenzlauer Berg, is great. Restaurants, bars, shops, supermarkets are everywhere.
Public transport is very close. Tram, U-Bahn, S-Bahn bring you to every destination in Berlin.
Frank is a great host, communication was quick, friendly and easy.
We will definitely come back!
