This was our first time in Berlin and my boyfriend and I are very happy that we stayed at Rainer’s place. The apartment is very easy to get to from TXL airport and is located in a quiet, safe neighborhood. The neighborhood is very walkable and public transport is only minutes away. Like many others have said, there are a lot of stairs in the building going up to the apartment but this just gave us more motivation to stay out and explore the city! The apartment itself is beautiful with lots of light. Overall we enjoyed our stay very much and would highly recommend staying here!
