Great place, great host, fantastic localisation.
We were 3 (with our 13 years old daughter). The studio is big, very comfortable and perfectly clean. 5 minutes walking from the beach and a nice and cheap taverna. It was very windy when we were there but one of the two beaches beside "Corali's" is well protected (the other is a kite surfer's heaven). Mario gave us a bunch of very good advices - things to do, places to see, tasty tavernas... He is discreet but always available when we needed him (even to play to tavli !!). He managed for us the rent of a car, which was useful to visit the island - one of the most beautiful Cyclads (maybe the most beautiful, now that Santorini is wasted by tourism). The roads are stunnings !
We hope we'll be back ! Thanks Mario for this memorable stay.
