Staff was very attentive. Breakfast was good! They let us hold our luggage there because we arrived earlier than our check in time. Provided us dining recommendations for Imerovigli and Fira. Enjoyable stay and spectacular views in the sunset rooms.

Well worth the money, the location is quiet, convenient (there is a market nearby where the snacks and drinks are very affordable). There is a path directly behind the hotel which allows you to walk to Oia and Fira. We stayed in the Sunrise suite, the view was beautiful, breakfast everyday was very good as well.

Beautiful stay. Hotel is very modern and luxurious. Room was spotless. Massive shower. Infinity pool with a break taking view, better than our hotel in Oia actually. Bed and pillows very comfortable. Towels and robes very plush. Staff were friendly and helpful. Included breakfast is delivered to room each morning and desired time and was exceptional. We got room service for dinner one night and it was also delicious and reasonably priced. We rented an ATV to get around the island for a few days and the hotel has free parking which was very nice. My only critiques would be that the pool was a bit cold (we stayed in Oia for two nights before one of one and that pool was much warmer/more comfortable for the May weather), it would be nice to have somewhere to hang towels/bathing suits outside on the patio, and a patio umbrella for shade on the sunbed would be appreciated. All minor things though. Would certainly stay again.

This is a gorgeous new hotel. The restaurant and the spa is still to come, but so far the rooms are beyond fantastic! This was the best hotel room we have ever stayed at!! Eva, the hotel manger, made sure we were very comfortable every day. I would highly recommend this hotel. Can’t wait to see it completed with the addition of the restaurant and the spa next year.

The hotel is very new and clean. It is located in a small town which is between the Fira and oia. So u can split the trail in two days. Walk to Fira bus station is only 20 mins. It is worth the price.

Idea destination for our honeymoon!! We came here the day after our wedding - Total relaxation at one of one. Romantic setting, the BEST sunset view from our cave suite. Impeccable service, the most comfiest super king bed, the banana bread for breakfast was scrumptious .. I need that recipe! from start to finish everything about our stay was beyond perfect. Every single staff member was helpful, cheerful - this has been our best hotel stay by far! I don’t like visiting the same destination twice but I would come back and stay here without question! Thank you for the best honeymoon stay.

This is a new property. Excellent attentive staff. Huge quiet clean comfy “cave”-room (we were in 202, one of the sunset view suites), with a spectacular view of sunset and caldera, and a refreshing private plunge pool. Strongly recommend renting a car (we did), as it’s not really walkable to much, and currently no bar or restaurant attached: it seems that they plan to add that at some point? Regardless, would highly recommend for room quality and view alone.

The property and the room was beautiful!! But it was too far removed from Fira and Room Service had a limited menu. The Cave room was absolutely amazing!! But people walking the path right outside the pool could see inside the room.
