Yes in fairness I forgot Mastahari but this is an ideal place as transfer time so close for airport but still far enough away noise wise, car hire either over to kefalos or into Kos Town only 30 mins each way. Then as well as Sponge Divers Island at Kalymnos try the volcanic island of Nissyros (also from the port of Mastahari) all my black and white original photos in our Corfu house are from there, from photographer called Artin, small island, white washed church, little back streets etc... very good day out from Kos. Yes would say Mastahari would be a fab option......
