René and Maria provided very helpful directions to navigate to their flat from the underground. I found my way there without too much trouble and René was kind enough to come down and get me (it was very loud outside and would have been difficult to give direction). He helped with my bags and gave me a tour of the place/explained everything. When I was going out, they always offered assistance with directions. There wasn't too much to explain since they'd provided such a great explanation beforehand!

The location is very close to Alexanderplatz, which is quite central, but about the stop itself, there wasn't much very closeby. Whenever I met friends it was not more than a few stops away, but not at the doorstep either.
