Maria and Ryan are welcoming and genuine nice people and we enjoyed our stay in their flat. We didn't have the chance to interract much with them since we spent most of our time exploring the wonders of the city or resting but when we did, they were both very cool.The guest room is simple but has all you need: a bed, high ceilings, a desk, heat, space and light. The appartment has a lot of charm and the location is great. My girlfriend and I love the Kreuzberg area and you're smack in the middle of it.
