The apartments are very cozy and exceptionally clean! There are everything necessary for living inside. The way from Tegel airport to the apartments is approximately 40 mins, the bus station is directly nearby, the underground is in 5 mins by foot. We spent about 20 mins to get to the center by public transport. Apartments are located in very quite and nice place, away from the noise and tourists. There are a plenty numbers of good cafes and restaurants. Supermarket is also in 5 mins away. Gerhard was super hospitable and responsive. He gave us recommendations during the all time of our staying. I highly recommend this apartments.
