Gerd is a well cultured and equally mannered host. Although it was nearing midnight, we were well received with lychee tea and rhubarb liquor.
We couldn't have imagined an apartment so impressionable from just reading the details and scrolling through pictures. It's huge and well decorated,a steal if you travel in a big group or 5-6. The apartment is located in a very quiet and peaceful district. At night, the area transforms into a place for romantic strolls.
I would suggest going along with Gerd's suggestions of places to go, would have gone too had I more time in Berlin. Had dinner with him on our last night and it definitely was better with his recommendations.
Will stay there again and if possible, convince him to give me a private tour of the city. :)
