We spent a week in Alex's cave house. We found Santorini very crowded and touristy (but beautiful) and to come back to the cave house at the end of the day was a great relief! It stays cool and has a fan (it was very hot when we were in Santorini), is roomy for two people, is very clean, is very private and has a lovely court yard with table and chairs. Alex was very accommodating with any requests we made and met us at the bus stop to show us the way to her lovely apartment. Finikia is a pedestrian only village, which makes it very peaceful but you do have to walk in (it's only a 3 minute walk from the car park) so make sure your bags aren't heavy or are on wheels! The wifi was a bit patchy on a couple of days but that may have been the ISP as our devices said the signal was very strong. The bed was a bit hard for us but we have old hips - it's probably fine for younger people. The shower was good and the kitchen quite well appointed although we didn't prepare much food as there are so many good restaurants around. Make sure you go to Mes Amis (10 minute walk) for the best coffee we had in Greece.
