We stayed in the apartment for a weekend break (3-nights) the place was clean upon arrival and the check in instructions fairly easy to follow. We checked in at 3pm and at around 4pm a locksmith randomly appeared and changed our locks - which was quite odd, as we had no prior warning. There were also no clean towels available until about 10.30pm on our first night - which wasn’t the end of the world and Klaus was very responsive to get this sorted - just a pain as we wanted to shower before our dinner. Another day there was an issue with the WiFi in the apartment - when I informed Klaus he was very quick to respond and help. Overall a very pleasant stay, I would definitely visit again, the location is the best part in a very cool and convenient location (walk everywhere!). Also there are no USB ports in the apartment, just an FYI if you forget your travel adaptor (like we did!)
Thanks!
