There is no elevator and the apartment is on floor 3. Not convenient if you have heavy luggage. For the private parking lot, you need a key to open the barrier everytime when you drive in and out of it. Not convenient if you drive a car here. Except above two points, everything is perfect. Warm and cozy apartment with soft and comfortable mattress. Prepared tea and chocolate make us feel at home. Fai and her friend are very kind, friendly and fast responsive. I strongly recommend her apartment to everyone who travel in Berlin.
