Staying at Mathias' apartment was a fantastic choice! As a host, he was VERY helpful, very quick to reply to messages and answer all questions. His apartment was exactly as described -- in fact, I think it may have even been better than described! It's a very comfortable flat, with everything you need and more! He provided very helpful, clear instructions for everything we might need, and things in the apartment are all labeled clearly, and sometimes include little helpful tips that you might otherwise miss! A really fantastic host, and a really fantastic apartment!
