The communication with Serena and her husband was very good. There are available in case of a problem and they are always available to offer help and they make sure that you feel good in the apartment.
They were very nice with us, they offered wine and breakfast and a car pass to park the car in the street.
The apartment was with many things you could need, the place was clean with air conditionned, close from the historical center and the beach.
The grotta is a nice place to chill out and have some good time.
I highly recommend.
