I liked my stay at Sabine's place a lot! Sabine is a super nice host. She was warm, helpful, and welcoming. I felt very comfortable and welcomed. At the end of my stay, she left a beautiful post card for me!
The room was clean, bright and spacious. There was everything necessary for a comfort stay: towels, bed linen, hair dryer, coffee machine, coffee, tea, etc.
The apartments are located 5 minutes away from U-Bahn Station Deutsche Oper, so it takes you about 15 minutes to get to the center.
