This is a fantastic place to stay. Karterados is only 20 minutes walk from Fira but in my opinion a more relaxing place to stay. The apartment is exactly as described, very clean and comfortable. Eleftherios is a great communicator and easy to get hold of. There is a fantastic restaurant in Karterados called Katerina's which is just up the road. We also found a hotel called Villa Manos 5 minutes walk that will let you swim in their pool if you buy drinks from their bar.
