Michalis' house is a real greek islandish white house with blue window frames and doors. Its up on a hill slope and has an amazing view to which you wake up every morning and can chill in the evening, drinking ouzo on the balcony and watching the sunset.
It's nice to have a car/scooter, but one can also reach Potamos and the house by feet from Aegiali Bay, which is a real nice place with some very nice beaches in the vicinity (you can walk to them or swim).
The kitchen could be a bit better equipped (especially more knives), but other than that the house is really perfect.
Very good value for money!
And also, I recommend Amorgos, it is a beautiful island where it feels like it was forgotten in time or time just stopped there. It is one of the most relaxing experiences of my life.
