Beautiful hotel, friendly professional staff. All felt very relaxing and chill.
They have a restaurant open throughout the day. I don't really understand how it can be profitable since the hotel has such a small number of guests. I hope it stays open though, as the food is excellent. It has a mixture of Greek and tourist food - and the best burger I'd eaten for some time.
The hotel is right next to the airport - you can see the planes take off from the pool - but there were only about ten per day, the noise only lasts for thirty seconds, and I didn't notice any at night... In fact I found being near the airport quite convenient: you're right near taxis and buses if you need ferrying to the port for the next leg of your journey, and it's obviously convenient if you arrive late in the day.
Added bonus: possibly the best supermarket in Mykonos is at the bottom of the hotel's lane.
It's quite removed from Mykonos town, so not the best hotel if you're looking to party. But if you're flying into Mykonos en route to another island, or want a few days of secluded luxury, this is a great option. Would definitely go back.
