Claus is a super friendly and communicative host. Our contact was very clear and smooth. He is really concerned about his guests and wants to do the best for them and checked proactively if everything is okay. The apartment was very handy and is located in my favorite area (exarchia). For me it was a bit too noisy cause it is in a big street. Nevertheless you have a nice view from the terrace and a park and a lot of nice streets around the apartment.
