We loved our stay at Dimitris & Evita's villa.
The views make this place, you can see Little Venice, Mykonos Town - it is beautiful.
The location is perfect for getting to the town and Ornos is only a 15 minute walk.
I would recommend you get quad bikes/car as the roads from the villa are VERY steep and not really walkable on a daily basis. (This is coming from a very fit individual!)
Evita was also the perfect host, she kept in touch throughout our stay and any issues or queries were quickly resolved.
Few things to note: the pool images are rather deceptive, this is more of a plunge pool. Also the water throughout the villa is saltwater including taps & showers.
Overall I would highly recommend this villa for your stay in Mykonos!
