A friend and I stayed with Klaus for 4 nights and had a really great experience. He was very accommodating, showed us how everything worked and even recommended things to do in the area. We ended up getting a bus up the mountain and going on a woodland walk back down through the vineyards, which we never would have known to do if it weren't for Klaus! Very thankful :) The room we had was lovely, a lot of space and great big windows for natural light. The only thing I would take into consideration is that there is only 1 shower/toilet for 4 bedrooms and this caused us an issue one morning when we were waiting half an hour for the shower - but 3/4 days without any issues isn't bad! The kitchen was absolutely fantatsic, we cooked 1/2 of the nights and everything was very easy to use, we even had access to a whole shelf in the fridge which was really good. The apartment was really easy to get to from the station, and there is a tram stop literally right outside the house. It's only a 7min walk to the metro station and this made our stay very relaxing as we knew we were never far from where we needed to be. Highly recommend this place!
