Kostas was a great host, picked us up at the airport and made sure we had water to drink, as folks don't drink from the tap there. Apartment was exactly like the photos. There was a lot of street noise since the house is on a busy corner, I just didn't realize Naxos town was so busy. That was my fault!
If you need to rent a car, go to the main square right by the house. Rent from Rental Center, we rented from them and another place on separate days and Rental Center was cheaper and a hundred times more friendly.
