My partner and I both had a great stay at Holgers appartment. The location was great, and located really close to a tram stop which was perfect to get anywhere. Although Holger was on holiday, he was very quick to respond to any of our queries and sent a friend over to help up figure out the washing machine! The appartment is located in a really nice complex, we met a few other people who lived there and they were all very friendly. We will be back there the next time we stay in Berlin!
