I'd highly recommend the windmill villas. We hired a car (recommended as the villa is nicely located in a quiet spot) so it was very easy to get around. We loved being away from the tourist spots but the location is still very good for getting around. Excellent if you value a quiet private space to relax. It had everything we could have asked for and exceeded our expectations! We loved the private pool to cool off from the sun. The maid service and breakfast was excellent and made for a very relaxing stay. Nikos was the perfect host, providing brilliant recommendations for things to do and great places to eat. It's probably possible to find cheaper places in Santorini but this was worth every penny!
