My husband and I had a fantastic trip! The apartment was super clean and beautiful. Babis welcomed us with some snacks and a bottle of wine. Greg was incredibly helpful and arranged a sailing excursion for us. My husband and I mixed up our dates and missed our flight from Santorini to Athens, which meant we had to stay an extra night at the apartment. Luckily, the apartment was not already booked and Babis and Greg were incredibly helpful and understanding. We rented a car and definitely recommend you do so as transportation options from the apartment are limited.
Also, Babis has two really cute dogs!
