The apartment is very well located, close to S-Bahn/U-Bahn, in the nice (but a bit more quiet than we expected) Prenzlauer Berg. Katja & Bernd were very quick and clear in communication. They couldn't welcome us themselves because we arrived late, but arranged something for us with the key, and there was a super nice card and fruit basket waiting for us at the apartment! The apartment is big, with a nice bathroom and balcony, is very clean and has everything you need for a stay. Would definetely recommend it!
