We really enjoyed our stay in Agrigente, the apartment is very well located (in the heart of the city) and very nicely decorated and clean ! Alice's parents welcomed us and they were adorable and very helpful, they gave us a lot of tips to visit the city.
Careful though, the kitchen is not really a kitchen (only one very tiny hotplate) and you can't really cook here.
The only negative thing about this apartment is that it is poorly soundproofed and that there was a concert just down the stairs, therefore we had to sleep with earplugs (very nice concert though !)
Thank you Alice !
