We (3 persons) spent 10 days over NYE at Kostas. The desert location as well as the view (and the clear night sky!) are certainly highlights even on a winter holiday in Syros. The house is beautiful and 3 person fit comfortably. You find there everything you need from kitchenware to warm bed linen and also bikes for people like us who don't drive! Kostas was very helpful and provided us with everything we needed at the same time as being a discreet neighbour. I highly recommend to stay at Kostas!
