We stayed at Ilaria's place for three nights.
The apartment was clean and very well-equipped.
It is located a short bus drive from the center, and cost 1/3 the price - so it was well worth it.
It has an A/C in the living room as well as in the double-bed room.
Unfortunately, in the two-bed room there was a ceiling fan that wasn't working - so we had to use a regular short floor fan that isn't as good. If you plan on staying when it's hot this could be an issue.
Ilaria was very welcoming and helped with everything needed for a pleasant stay.
We had an issue with the fan so she replaced it immediately, and she also helped us to order a taxi back to the airport.
I would definitely recommend staying at her place.
