We met Hubert only the very last day when we handled back the keys, but he was really great. Communication went really easy and he helped us with directions and how to get the keys for the apartment. He kept in contact with us every time we needed something. The apartment is really big and you will get a lot of privacy. We were 4 people but it was more than enough. It is also well located, just a few steps away from U-Bahn Schwartzkopffstrasse station. The area is quite nice too with 24h shops and restaurants. The pictures of the apartment don't give it enough justice, as it is much bigger than what it seems. I would surely recommend Hubert's apartment when you come to Berlin. Hope to come back again!
