Wow, just wow. The views from the apartment are some of the best I've ever seen.
We did 2 days in Oia (other side of the island) prior to coming to Chantals at a 5-star hotel and paid 3x the price. Hands down Chantal's place was MUCH better accommodation, space, location AND views.
The location is perfect. It's in Thira, which is a less than 10 minute walk to Fira, the part of town where lots of shopping, restaurants, bars and a lot more.
Chantal was so so sweet from the kind welcome to the chef prepared breakfast each morning on the patio to the pick up and drop off to airport.
If you are headed to Santorini, this is an amazing option. We'd go back in a heart beat.
