Our stay at Villa Giorgos was very pleasant. He and his family (and the family dog Tito!) are caring people who live right under the studio. They offered us homemade cake and cleaned our rooms - something we wouldn't even expect at a airbnb. The location is very close to the beach and restaurants, shops, car rentals, etc. From the balcony you can see the nicest sunrise above the sea - if you wake up in time ;)
I'd totally recommend the place to anyone who is looking for a decent but inexpensive place at Kos island.
