We would have enjoyed our stay at Mauro & Elena's place if not for the heating (see below).
The flat was very clean and modern, had all the amenities and eating out on the patio was excellent! The internet was fast (500Mbit) and reliable, but we had trouble with cellular signal in the flat.
The weirdest thing about our stay was the heating. In short we had to choose between being cold (this was April) or using a mould-infested AC unit for heat. Both of us ended up getting a cough, not sure if from the cold or from the mould (not covid, we did a test).
Full story:
When we checked in we were told it's not possible to regulate the thermostat and that we can use the AC for heating. I thought it was a bit odd, but.. ok.
This was the first week of April so outside was warm during the day and chilly at night, however inside the flat it always felt like being in a fridge. The air was around 18-20C, but the tiled floor was very cold and made it feel closer to 15C (which I imagine is great during summer). Both of us needed to work remotely for some of the stay, so we couldn't just go outside for warmth.
The thermostat was configured to warm the flat a bit in the morning and evening, the rest of the time it automatically changed to some low setting. It was indeed not possible to change this (fancy "smart" technology). So, as instructed, we tried using the AC to heat, which was slow to heat the place and smelled a bit weird. The smell turned out to be due to a significant amount of mould on the inside of both units.
I think the smart thermostat is a good idea (most guests would be outside most of the time, so no point emitting co2), but not providing a way for the guests to temporarily override the setting is in my opinion not acceptable.
