Heinz's apartment was lovely! We arrived late after the office was closed, however, after a phone call to Heinz he quickly arranged for us to receive the keys and check in. It was so kind of him and much appreciated after a long train ride from Amsterdam. The apartment was laid out nicely with the two bedrooms separated by a sitting room. The apart was very spacious. We found nice restaurants around the corner and we enjoyed walking to local sites. We had a wonderful time it Berlin and I would highly recommend this apartment. Heinz was a gracious host, which made us feel comfortable and at ease while visiting Berlin. Thank you Heinz!
