Henrik’s apartment was perfectly suited to our needs. Communication was almost instant with regards to any queries we had and he was more than accommodating to arrange that we drop our bags off early. Sven was actually the guy who met us at the apartment and was absolutely great, we met his two dogs which were very friendly also.
The apartment itself is 2 stops away from Alexanderplatz which is one of the main transport stations and we were perfectly situated for making the most out of our few days in Berlin.
