We had a wonderful stay at Fournos studio. The place is at a great spot : calm and away from the port agitation, but very close to be able to walk there to go to the restaurant or grothery shopping.
The studio is very comfortable and has everything you need, it's quite big (Ithing it looks bigger that on the pictures).
Kosta and his wife were very nice and helpful (they picked us from the boat and even gave us family grown cucumbers).
I highly recommend this place of you want to stay in Amorgos!
