The issues with this property could so easily have been avoided and were a result of the lack of care and apathy from the host.
Our biggest problem was security. The building has several listings hosted by Homm. Each flat has a keypad for access and the key code corresponds to the number of the flat. Meaning that once you know one code, it is obvious what the codes are for the other flats.
We asked the host, to change our code. We were initially told the keycode gets changed every 15 days (clearly untrue, it wasn't a random number), then we were told it would be changed after our checkout, useless to us. When we asked if we could change it during our stay (10 days), we were told they were unable to change the code.
We asked them if they believed it was safe, given that we could access any of the apartments and any of the guests in the building could access ours. They agreed with us but told us "There was nothing they could do".
All in all, a host that doesn't care at all
