Location, location, location. We could have stayed all day on our balcony gazing over the lovely Skinopi bay, occasionally coming down the 10 steps or so to the water to snorkel and have a little swim. And in fact this is exactly what we did for the first 3 days. It was just too nice to leave. The house is small but clean (cleaners came half way through our one week stay) and fully equipped so we cooked some of our meals and ate them watching the sunset. There is a double mattress - rather than the silly two separate beds which many Greek b&bs tend to have and a very nice spacious bathroom.
Sophia runs a well-managed tourist business located right next to the ferry and we rented our car there. They also give very useful tips about boat trips around the island (which they can book for you), restaurants to go to or places / beaches to visit. Yiannis in particular gave us a slew of tips, all of which were superb. We will certainly be back!
