My wife and I stayed here for a couple of nights recently, and it was great. The staff were very friendly, and extremely helpful in giving us information about Santorini island. We rented bikes for one of our days, which needs to be arranged a day prior. The rooms were spotless, and the air conditioning worked great. Each room has a patio/sitting area where we were able to enjoy our complimentary breakfast, which was the usual for Greece that we've experienced: bread, cheese, ham, yogurt, cereal, coffee and orange juice. The hotel also has a great pool area with loungers and a pool bar; great for relaxing in the sun.
The only drawback of staying here is the location. There is a supermarket two minutes down the road, and a seaside restaurant about a five minute walk from the hotel. Other than that, there's not really anything else as far as restaurants go. Kamari is a good 45 minute walk, so options are limited if you don't have a vehicle/motorbike/bicycle.
Overall, a great place to stay, with great value.
