I stayed at Ute's place for a couple of nights on a short trip to Berlin. It's in a great spot at the southern end of Kruezberg, with an amazing deli market nearby and loads of restaurants/bars, plus the underground station literally outside the front door. Check in was really easy, although I didn't meet Ute as she was away travelling, Natalie instead was wonderful and explained everything that was needed. Would definitely recommend for single travellers exploring the city
