My boyfriend and I resided at Claus's apartment for 8 days an absolutely loved it. It was hard to leave the place because it was simply so comfortable and you felt right at home.
We would highly recommend Claus's apartment to future travelers - the photos don't do it justice, it was a amazing.
As for Claus, he was extremely helpful on the day of our arrival and gave us a load of information for local food, drinking and sightseeing places.
