The hotel itself and the staff were great. The main issue we had was the placement of the hotel on the island, especially if you're not full board, as there are very few (well, one) restaurants nearby. Also due to the roads and mountains its really further from Kos town than you would think. Even Kardemena is a 45 min walk, or bus or taxi ride, and it has many restaurants but its a bit run down and tacky compared to Kos town or other areas.
On the plus side, this hotel has excellent pools and staff. If you're full board or have your own car then this hotel might be perfect for you. One more thing: the beach here is rough sand.....go to Kephalos area beaches like Bubble beach, to get really proper beaches. (there are buses that can take you there). And please go see the Asklepion and Kos town Roman villa if you have any interest in history at all. And Nysiros island for the volcano!
