I didn't meet Nadja, but Breditz was fantastic. When we arrived he gave us instructions for everything we needed to know, even gave us a map marking the best places to see and where to eat. This was very helpful! The apartment was exactly as it appeared in the photos. The backyard was beautiful, we wish we could have stayed longer than 2 days to enjoy it a bit more and use the bikes to ride around town.
All in all a wonderful experience!
