Katharina and Nicholas are super sweet couple, very helpful, responsive and open-minded. I really felt in love with their apartment! Every single detail is perfect, very stylish design, sometimes you feel like you’re living in the contemporary art museum, but it’s really nice. And also the place was perfectly clean. They have everything what you need in their flat. Especially I liked the energy of this place and interesting chatting with hosts. I wish I could stay there for longer period.
