We enjoyed our stay (8 persons) at Daniela's place. Check in was smooth and her partner who was working at the reception was very kind. He offered us some much needed coffee and cold water (as well as Daniela on the day we checked out).
It's important to know that this place is actually a sort of hotel with separate little bungalows. The bungalows are what are on offer here. They're cute, not extravagant or lush, but just right for a couple of nights. They all come with a little terrace/balcony and a view over the lake (which you cannot swim in unfortunately). It's a good place for a larger group, that's for sure. Each room has it's own air-conditioning unit which is REALLY lush if you're not used to sleeping in hot weather. We just slept, showered and got changed/ready at Daniela's place.
Because it's a type of hotel they do come tidy up the rooms and surrounding daily.
I had a good laugh at the decor which is classy and a set in baroque style. I liked it. The bed was comfy (Room #8). And my communication with Daniela was smooth despite the language barrier (airbnb and google translate will help you).
If I were ever in the Pergusa area again, I would probably see if Daniela had some availability. The cafe's on the main street nearby were yummy and very Sicilian...learn a few Italian words...your experience will be much richer.
