I spent three nights at Harald's place. It's located about 10 Minutes from U6 Stadthalle, then, all point of interests are just a few stations away. It is very quit, in the backyard, and very, very clean. It is nicely and warmly decorated. I enjoyed myself very much. Harald's a great host. Communication was easy and fast. Check-in w/o any problems. Check-out the same. I can only recommend this apartment and Harald as a host and hope to be back soon!
