Me and a friend had a wonderful stay at Diafani. The apartment was clean and comfortable, and the view from its balcony and living room was outstanding. The sunrises -and moonrises!- are spectacular there. Diafani is an unremarkable village, but a great base for your excursions around northern Karpathos.
John's parents were kind and gracious hosts. They picked us up at the port and -more importantly- helped us move our luggage to the car (there are some steep steps leading up to the apartment) on the day of our departure, and then invited us into their home for a cup of coffee. Important detail: It was 6:30AM. On a Sunday.
Wonderful people.
