8.4/10 Very Good! (135 reviews)

Very friendly and helpful staff, some of them standout so much that I needed to learned their names to mention them in review... Katia, ( always gave a kind word for my daughter and made her feel at home by noticing her pattern of food, my daughter doesnt speak italian), Enza ( she was on the top of our food arrangements) 2 men called Vito, very helpful and they made the best coffees. We were extremely please with the room as it had 2 toilets/shower rooms and our room had a balcony with sea view to died for.... I cant wait to go in Summer. Best deal, it is to rent a car, as this place is 11 minutes from the mains places.

8.8/10 Excellent! (492 reviews)

This is less than a mile from the airport. A nice place to stay to end your trip and make it an easy 5 minute trip to the airport. They have a pool and spa and gym and restaurant but we didn’t have time for any of that. Water and kettle provided in the room. Wifi in the room was not good however due to weak signal.
