Maison Muse

10/10 Excellent

"Make sure you get direct contact with the manager and staff at the hotel as the expedia site doesn't provide the correct directions to the hotel The manager Kosta was a true gentleman with a wealth of local knowledge that was of great assistance in navigating the island and getting the best deals on day trips and experiences The hotel is in a great central location and the pool is a must on hot days Highly recommend the hotel and staff when visiting Hydra"

SEAFOS Luxury Resort & Spa - Limited Edition by Leonardo Hotels

"What a wonderful day we had at the hotel Miranda. From the moment we walked in, the staff was gracious, and the property was beautiful.

Bratsera Hotel Hydra

"Everything was stunning! We’ll return"

Hydra Beach Resort

8/10 Good

"We really enjoyed the all-inclusive part of the resort. The reservation-only restaurant at the resort was terrible, but the buffet was consistently good. Probably would have stayed a couple of days less than we did so we could explore more than we did, but it was a nice time. The views can’t be beat, and the weather is perfect for the beach and pool."

Thermesea Luxury Lodge

8/10 Good

"Nice spot, clean rooms, quiet for a good sleep"
