We enjoyed our stay at La Mer Cave House. It was definitely an experience we were glad to have in Santorini. Vasilis was extremely helpful with getting our luggage up and down the stairs... and there are a lot of stairs! The view was amazing! Maybe we didn't read closely enough, but we were surprised to see the bathroom was outside of the house. It was private, but once in a while a tourist would wander by and could potentially see you going in and out of the bathroom.
