Karsten was amazing. He was very flexible with checking in, and when we arrived he sat down with us, explained how the underground system works, and provided us with maps of Berlin on which he pointed out his favorite spots to hang out as a local.

The apartment itself was also great. For my friend and me the space was perfect, and the location as well - in a nice quiet area with walking distance to great restaurants and bars, and a short underground ride to the city center with many of the tourist attractions.

I highly recommend the apartment and would definitely stay here again!
