Heinz gave clear directions for checking in, which was simple and easy at an office very near the apartment. He was very attentive and easy to work with by text and email, although we never actually met him in person as he was out of town during our stay. The apartment was lovely, spacious and filled with light. The kitchen had everything we needed, and the apartment has a washing machine in it. The location is fantastic, a block or 2 from Brandenburg gate, right next to the American Embassy. The only negative really was 1 bathroom for 5 people. We would be happy to stay at this apartment again in the future.
