I stayed one night with my family, the staff are really fantastic, friendly and efficient. We arrived around 6pm and were given the ph room, the room was spotless. It was dark outside and there were very few lights inside. I understand the choice of artistic installations but at 6pm you don't want to be in the dark, furthermore upon our arrival we were greeted by a strong smell of sewage which we managed to get rid of after letting the water run a bit.
Let's say that despite the particularity and kindness of the owners, I would not recommend this accommodation, sorry.
