We had a great time at the Secret Gem. I didn't find the walk to the Airbnb that difficult. Like everyone had said, the sunset view is unbeatable. And we especially appreciated that Chris and his wife arranged transfers for us every single day. The last day before we left, they held our luggages for us, and then arranged for a transfer to pick us up from Fira to the airport, and then had another car drive our luggage to the airport for us. It just made everything so much easier. Finally, the daily breakfast was absolutely delicious.
Chris is a busy man. We had some difficulty getting responses from him via Airbnb app. But once we've checked in, he was very responsive whenever we needed him.
I would definitely recommend this place and would love to come back again!
