We came 5 friends to a vacation in Berlin. The apartment's location is absolutely amazing: near zionskirche at a quiet street but only one minute walk from kastannienalle, a very hip and fun street. Rosenthalerplatz is only minuts away by feet, shopping areas and many restaurants.
Robin was very flexible with check-in and check-out hours and it really helped us since we took night-flights.
The apt is at the top floor so elevator was critical to us. It didn't work when we checked in but got fixed after a short hour. We were given at first only one key, and since we were 5 visitors we knew we couldn't manage with less then two. At the next day we got another key.
The beds are very comfortable and the apartment has 2 amazing balconies so the apartment is filled with light and sun. Kitchen is great and the shower room is big and comfortable. All and all, after a few small adjustments, we had a great experience at robin's apartment
