Great accommodation; one of the best price-quality for 4-5 people in expensive Mykonos i think. The location is perfect: great view, windy, walking distance of the citycenter, at night you feel the city and hear the music in your garden/balcony, which is lovely; when you close the door, you only hear silence :)
We love having a jacuzzi and use it daily. There is also a lovely catfamily from nextdoor. Airco in every room is great and silent fast cooling.
Apostolos is a great host with quick and helpful responses.
Remember: there is no dishwasher and inside its a little bit basic look and feel. Walk up and downhill was ok for us but you have to be really careful with the traffic. As adults, but especially with kids.
