Me and my girlfriend went to Santorini for two days. We couldn't have asked for a better host or place to spend it at.
Margarita was amazing and always saved us with transfers when the very unreliable busses didn't go. She was very easy-going and service-minded, and superfast to reply.
The room was nice and the location was amazing, especially if you want to avoid all the other tourists and meet the locals. It's 30 minutes walk to Firá but if you ask Margarita she'll gladly fix a affordable taxi for you. There's one restaurant just 50 meters from the room with tasty food and a charming waiter, ask him to try his own liquor, very tasty.
All and all an amazing host and a great room!
