We have visited Casa Azzurra and it was just great....a calm place above the sea, at night you could only hear the waves. On the terrace, you can look at the sea and on the other side of the bay, there is Catania and the Etna. The apartment was big enough for 4 adults, especially with the two bathrooms. The neighbourhood was really calm, except for the weekend, when lots of italian residents came to meet at their pools in the condo ;-) The pool is nice and sunny and filled with seawater (no chlorine :-) ) If you want to go swimming in the sea below the apartment, bring swimming shoes, there are shells growing on the stones. There is a pizzeria at the entrance of the gated community, but for anything else, you really need a car. We can recommend the restaurant at Hotel Il Triangolo in Agnone Bagni, they have great seafood! And also, you can go for a swim at the sandy beach.
For check-in, we contacted Ketty as we were instructed before, and she met with us and showed us the apartment as soon as we arrived from the airport (thanks again!) So- just bring some mosquito repellent, and then enjoy some red wine on the terrace of Casa Azzurra :-)
