We stayed at the Marana for 6 nights and had a thoroughly enjoyable time. The staff were professional, attentive and above all friendly with nothing being too much trouble.
The Hotel seems very new as it was immaculate. I booked a garden suite but I think it was upgraded to a junior with a lovely view of the pool and garden ( I had contacted the hotel direct as it was my girlfriends **th (!) birthday ).The beach ( although not the prettiest in the world is free to Hotel guests whereas some public beaches charge 40 eu pp per day for loungers) is just 5 minutes walk.
We did not eat at the restaurant as we had a car (free, underground (cool) parking) and wanted to explore but other guests told us that it was excellent.
If I were being tortured to find a negative, it would be that the room did not have a kettle (personal and petty maybe, but nice to have the freedom).
The pluses are numerous but it is the little things that count - notwithstanding all of the above - we had a late flight and had to check out at 12 but the hotel have a facility whereby you can store your luggage till needed and made available a room with a shower, etc to change when needed (no charge, just book).
All in all I would recommend this hotel very highly and have no hesitation in returning. A fantastic location for exploring (beautiful Porto Rotondo just 5 minutes drive). The local Marina of Marinella is very quiet but has a couple of lovely restaurants.
