I stayed at Paul's Appartement for 4 days and nights. It's very clean, beautiful and cozy. The bed is comfortable. The room also has a sofa and 2 armchairs and a table so it feels like you have 2 both - living room and bedroom. Paul also offered me a bike, it's really nice of him! The flat is located in a calm peaceful area and took me around 40 mins to get to the city center. Buses are 24/7 in Berlin. Paul was very kind to show me everything in the flat and it was very convenient that he lives just upstairs. The flat is really well thought, and it has tasty coffee in it. Thank you!
