Premium service
We rented a 51ft Oceania from Cala dei Sardi Marina. The whole marina was run by the charter company which was excellent. They had air conditioned reception for check in and then areas with chairs and loungers to relax and swim whilst waiting for the boat. The boat was very diligently cleaned inside and out before boarding and the charter company were available via WhatsApp for any questions during the week.
The only negatives were the toilet facilities at the marina were very small (1 toilet and 2 showers) and you may not get the boats till 6pm.
The food at the restaurant at the marina was excellent for dinner , highly recommend Booking.
The food shop that the shuttle goes to is limited and small, it is better to get a taxi to the large Conad
