I stayed here with my girlfriend and two other couples. The house itself is great, with well-sized bedrooms, private bathrooms, a full kitchen, and plenty of common space. We were all very comfortable with plenty of room, and the view from the terrace is excellent, especially at sunset. Our host very generously arranged to have his housekeeper pick us up from the Old Port, but we did have a few minor issues during our stay.
Our tiny trash cans quickly filled up, and we didn't know what to do with our filled bags. We were told the housekeeper would take care of it but they were never emptied during our stay, and we could not find any place to dispose of them near the property. At one point we asked if there was a broom in the house, and we were told the housekeeper would bring one, but that also never happened.
Lastly, I highly recommend renting a car if you decide to stay here, as the house is not really within walking distance of anything. My group rented one but ending up returning it as it was unable to handle the extremely steep hills of the surrounding area, so we opted to use taxis. The villa does not have a name, and our host did not really give us a clear answer as to where exactly we were, so we had an extremely difficult time telling taxis where to find us (there are no street names or addresses in Mykonos).
