We had a great stay at Francesco's place. Francesco himself met us and showed us around. Really nice person and quite flexible. Gave us useful tips.
The apartment is very clean and specious. It has everything you need for a relaxing stay. Beds were very comfortable. Kitchen was really well equipped.
In terms of location - city center of Agrigento is walking distance (around 15-ish minutes). Both entrances to the valley of the temples are also at walking distance (1 to 1,5 km). Free parking around the building. No shortage of space. 2 big supermarkets in very close proximity (1 m walk).
Definitely a great pick!
