Oliver's place was in a great location. We were travelling from Schonefeld airport and it was very easy to access - a 35 minute journey straight to Schonhausser Allee station by the S-Bahn and then we were just a 10 minute walk to his apartment. The apartment was very spacious and clean. Despite being in a central location, the apartment block itself was very quiet at night. Oliver was very flexible with check-in/check out times which made the stay a lot more smoother than if we had stayed at a hotel. We did have a small issue with the apartment door (Oliver left keys for us at a local shop). There is a knack to opening the door where you had to pull the door towards you then turn the key to open. After a few attempts we got in, however, it would have been helpful to have been made aware of this beforehand. The apartment is up a good few flights of stairs, so it can be a struggle if you have a lot of luggage. However, all in all, we enjoyed our stay here and would recommend it.
