The villa is superb and nicely decorated and George a very kind host. He picked our group up at the airport, advised us on what to do on the island and even gave us a ride back to the airport the day we left. Communication with him was very easy since he replied very quickly to every matter regarding the house or our trip in general.
You will need a car though as the villa is a bit out of the way (unless you are planning on spending your time entirely at the house).
To put it in a nutshell: we had a great time at Mykonos Art Villa!
