The property itself was fine and in a nice location. There were two issues.
Firstly it was cold. I asked the host for instructions on how to turn up the heating, there being many signs saying don’t attempt as it will disconnect the heating from the Wi-Fi. I was told to look for extra blankets. Consequently I had to walk around the apartment during the day wearing many layers and my outdoor coat.
Secondly the flat was poorly equipped. No cafetière , no toaster, no roasting tin to cook anything in, and the smallest ironing board I have ever seen.
