We were a bit cautious because of the mixed comments. Davide was not there at the check-in, just the houseowner, who did not speak english, which is very difficult if you do not know italian.
We had a closer look at bed, bathroom, etc. but everything was quite clean.
Just the kitchen was a problem because oven and other things smelled very bad and apparently they have not been cleaned a long time.
The house owner seemed grumpy and paranoid, because the door of his appartment was always open when we came down/went up. (Which happened already at an italian host; but of course it is not welcoming)
All in all, it was a nice appartment. Especially the big house and the view on Etna/the sea.
