We had an overall good experience at Guido's place. It's a small house in the middle of a charming condo. It's quiet. There are some stairs to get to the place.
The heating wasn't working when we got there, and it was unusually cold for May. Guido was a bit dismissive about the issue, telling us to just use the AC, but we insisted (it was really cold) and he quickly came over to fix the heating, which turned out to take only a minute to do.
Some power outlets were problematic, not completely broken but close enough that they weren't usable. I don't know how to explain it exactly, but when we tried to use the power outlets in the bedroom they kind of sunk into the wall like they were loose. We were unable to use those and some others. There was also a moderate ant problem in the bedroom.
Some kitchenware was not only dusty, but dirty. Still, the kitchen is well equipped. Bathroom was nice. The shower is very small but works well, water is hot.
Guido was very responsive. His replies were quick and he helped us book a taxi for an early flight when we left.
