I strongly recommend this AirBnB for those willing to go a little off the beaten path in Santorini. The canyon location and cave interior are very cool. The rooftop terrace was very fun for sunsets. We were comfortable and used the various amenities (AC, shower, mini fridge) without issue. It was an excellent value.
The cave house is a 10-15 minute walk down a dirt road with some incline. We used a taxi for our check in/check out and the bus from Emporio for all other activities around the island. This worked fine, but may tire some people out. It is not for everybody, but it is great.
