On the morning of the check-out date a guy from City Relay's (who I've never seen not spoken to) contacted me via a messenger and started begging me for a good review, reasoning with "it would be very important for his promotion".
I paid for the "late check-out" service so I could move out at 1 pm. First, at about 12:50 they contacted me and told me that the guy who would get the keys is running late and would be there by 13:15. Tnen, at 13:14 that guy called me and informed me that he can be there only at 13:45 and not earlier. I told them that I have no time to wait, and that I had paid for the service. So he suggested I bring the keys to a corner-shop in 5 min from the flat so their friend could keep the keys.
Not satisfied at all!
