The studio is indeed charming and the roof terrace great, you probably can make the most out of it during warm month. We stayed there for a weekend. Martin is very nice and welcoming, he gave us lots of tips and explained where to go and what to do.
I think it is a good place for couples, we were two girls and had a hard time not making to much noise, the house is not soundproof. Which is not bad at all, but we had a guilty conscience about coming to the studio late.
All in all we enjoyed our stay a lot and can only recommend the studio.
