I stayed four days at Steve's apartment and can say: I enjoyed myself very much. It's located about 5 minutes walk from metro station "Stadthalle". There's a supermarket just around the corner. The apartment is spacious and equipped with everything you need for a pleasant stay. It's perfect for a couple, but can accommodate up to four people. It's nicely decorated, WLAN is fast and the whole apartment is very tidy. As it is located in a quiet side street, I couldn't hear anything and slept very well. Communication was fast, and all questions were answered almost immediately. Check-in is very easy, as there is a key box at the entrance door. I can really recommend this apartment and Steve as a host!
