Gorgeous spacious apartment, we all loved it :) Everything was in good working order, and we had everything we needed plus some little extras (like the coffee machine) that made our stay that bit better.
Very close to the u-bahn and to a supermarket too, as well as an extremely nice kebab shop :)
I don't speak German, but that wasn't a problem at all, everyone connected with the apartment spoke good English, so I didn't have to worry.
