The air b&b was a nice place to stay and we would recommend it for its close proximity to Ornos beach and its many restaurants, as well as its charming and unique style.
The air b&b is tricky to find, but look for the white couch and dining table outside. It is one unit in a complex right beside Corfus Hotel. The place itself is pretty neat as it is a traditional Mykononian "cave" house and is exactly as pictured. It was plenty of space for us (4 adults). We liked having a common area to hang out both inside and outside the unit, and the pool was also great! The place is well stocked with spices (likely left over from other guests), cleaning supplies, and kitchen appliances. It is a very good location, walking distance from Ornos beach, and a quick drive from Mykonos town and other beaches. There is free parking outside the complex.
Dimitris is a very hands off host but we didn't find this to be a problem, especially since he responds very quickly to his messages. He provides all the info you need to know the day before and is overall a helpful host.
However a 3 star review is warranted for our stay. One star was removed because we felt the house was not as clean as it could have been. A second star was removed because of the host's disorganization. The next guests came in while we were still at the unit - 4 hours before our check out time with no notice to us.
