Stayed in the appartment with my parents and brother for 5 nights and had a nice stay. The host was there at the agreed time for the key exchange, it was clean and had basically everything we needed. The appartment was sometimes a bit noisy though (could hear other people talking and partying in the appartment below us) but hey I guess thats normal in a city :) The location was a little bit out of the (old) city center though, but then again: also a bit less crowded!
