We had a wonderful time at Tina and George's place. It's pretty much as advertised - the pictures, descriptions etc, and is very professionally run. It's extremely clean - and cleaned every few days with new sheets and towels - and has everything you could want for a week, which is how long we stayed. The free transfers to/from airport was a nice bonus since it took one less worry away and made everything really smooth on arrival and departure.
We had some concerns being so close to the airport but first of all it's not a busy airport, and the noise really didn't bother us. In fact, unlike much of Santorini, the location is very peaceful. I would say it's perfect it you have access to a car and want to get away to relax in a nice location at the end of the day - especially families with kids who will love the pool. While it's nice to be close to a beach, the beaches in Santorini are not all that special and the local beach here isn't necessarily one you want to spend much time on. There is, however, a great local seafood restaurant less than 5 mins walk away on the beach which was very friendly and great value.
We were two families sharing the accommodation and we all loved it - highly recommend it. Again, it's away from the hustle and bustle of Fira and Oia, but if you have a car you'll get exposed to that plenty and it's a great place to come back to after a busy day and relax by the pool or barbecue area.
