I spent 3 days in Mykonos at the Apartments Rania.
Made the reservation with Nikolas, that I didn't meet, but I did meet Alexander who was a great help for "what to do-where to go" in Mykonos.
The room was very good for a guy traveling alone, so I am well satisfied. The location is perfect, just up the street from the touristic area of Mykonos town.
I would definately stay at Apartments Rania if I had the opportunity of returning to Mykonos.
