Me and my friends spent a few nights in Martin's apartment, which is newly renovated, really cozy and exceptionally clean. A good sleep is guaranteed by comfortable beds and pillows. You'll find everything you need in the apartment. The location is perfect for exploring Kreuzberg and it's also easy to reach other parts of the city by public transport. There are plenty of restaurants, bars etc. nearby. However, It's a quiet street, so traffic noises won't bother you. The only downside for us was that there was this certain type of smell in the apartment, like in a cellar. It may be an issue if you are sensitive to this type of smell. Martin is a very nice guy and easy to reach. He was really helpful and everything went smoothly. Thank you!
