We booked this hotel because it seemed to be the best price in mykonos. Because of this we weren't expecting much but we were pleasantly surprised. The hotel is very modern, bedrooms are great, swimming pool is big, lots of comfy sunbeds, pool towels provided and a pool bar. Staff were extremely friendly and helpful; free transfer from the port and airport, assisted us with booking a moped, and were happy to answer questions. Breakfast was complimentary, offering cereals, pastry, eggs, sausage, bread, juice, tea and coffee.
Location was decent enough, 1 minute walk from the bus stop going into town (although we never used the busses) and right in between the town and the main beach locations (paradise/Ornos beach) meaning it was easy to get to different areas. I would suggest hiring a bike/quad though as the hotel is at the top of the hill so the walk back would be quite long. There's also a few good restaurants very close to the hotel, and a good supermarket.
All in all a great stay, I would definitely recommend staying here instead of splashing a lot more money on somewhere in the main town.
