It can be tough to escape the ever-present throngs of tourist in Oia. Casa Sofia was conveniently located on the most-photographed cliffs of this part of the village, tucked behind the infamous blue-domed church. It could not have been better situated - a short but steep uphill walk to the main pedestrian strip with shopping and restaurants. If you're fit and want to give your legs a daily workout, this is the place for you. As a cave flat, it was nice and cool all day and night, but for the same reason was a bit damp. Wet bathing suits, clothing or towels need to be hung outside or they will never dry. The rustic charm and novel thrill of sleeping and waking up on the cliffs overlooking the Aegean Sea more than made up for it. Maria was an extremely friendly and courteous host - providing us with a wealth of tips and advice to avoid the crowds and see some of the less trodden sites of Santorini. When we indicated that we wanted to take a catamaran cruise, she took care of the booking, and met us at the flat on the morning of the tour to accompany us to the bus transfer to the port. I cannot recommend this sweet little flat or Maria highly enough!
