Kostas was very friendly and helpful. He helped us with a late checkin and a really late checkout. He arranged for us to rent cars at a very good rate as well. As written in the description, the cave is small and has just a fan. Without air conditioning, it got a little stuffy. The bathroom in the other room is extremely small. The part we enjoyed the most and spent a majority of our time in was the huge sitting area outside the rooms. We highly recommend that you book cars before or as soon as you get there.
