Visited Berlin with my daughter and a friend. Great city. We all enjoyed ourselves. Norbert's apartment is unique, and well designed with many conveniences, and is located in a nice part of the city. It's easily and quickly accessible via public transport to most places someone would likely visit in Berlin. If you have 1-2 people staying here then the apartment is lots of fun , if you have more and want some elbow room you may find it a bit too cramped. Norbert put a lot of thought and effort into the place and I have no doubt he would do whatever it took to make any visitor feel comfortable and to insure they have what they need. His quick responses, attention to detail, overall graciousness and hospitality will be the things I remember most.
