This was our first time to Santorini and we had a great time staying at Katerina's place. It's a very authentic place located in a very cute and friendly neighborhood. We rented a scooter and were an easy 10 - 15 minute ride from most parts of the island. The spot is tucked away so it's quiet and comfortable. Katerina was very responsive and helpful throughout our stay and we're very grateful for that. Overall - definitely recommend!
PS - the courtyard is home to a few cats which everyone in the neighborhood takes care of - there's a small one, all black, we named her Stella - give her a scratch behind the ear from us and tell her we miss her.
