Karsten's apartment is very cool and quirky. He has made great use of the space. I loved how the bed was separated even though it was in the same room. Very clean and I felt at home. Karsten was away at the time we checked in but he put us in touch with a lady named Natalie who met with us and we could message for the whole duration of the trip if we had any queries. Karsten was very flexible when it came to check out.
I would highly recommend Karsten's apartment!
