Summary: The hotel is in a perfect beachfront location and, being the last property on Platis Gialos Beach, offers a quieter atmosphere than the other hotels nearby. The rooms are modern, comfortable, and each has a private balcony. The complimentary beach sunbeds are a fantastic perk—something we really appreciated in Mykonos. Breakfast is served at the table at the restaurant near the beach with plenty of choice, and the staff were always friendly and helpful. Platis Gialos was the perfect base for us as a couple, with excellent beachfront restaurants and easy access to both the bus stop and the water taxi. We would definitely stay here again.
