The apartment was even better than it appeared in pictures on the website, and much larger than we anticipated. 2 bedrooms, both with King beds - large living, eating area - and plenty of space in between the rooms and bathrooms. Even though the apartment is subterranean, it was VERY bright with the large windows. There was no air conditioning, which would not be a problem at all since the apartment is subterranean - heating is provided via very effective radiant floor heating. Doerthe was the perfect host, providing great directions on how to get to the apartment as well as providing information on local restaurants, pubs, shopping and how to get to different sites around Berlin. His hospitality was outstanding, with a few nice gifts upon arrival that made us feel very welcome. The Kreuzberg location is fantastic - with many restaurants, pubs, boutiques, and U-Bahn stations within the immediate area (literally, within a 2 minute walk). I highly recommend this apartment as well as Doerthe as a host!
