My friends and I stayed at George's cave houses for three days in Oia and had a perfect experience. Transfers by both donkey and car were seamless and George was the most helpful host with plenty of tips and advice on things to see. The view from the house was incredible, and the house itself was so beautifully maintained and very clean and spacious fully stocked with everything you would need. The location also was perfect, very convenient to get to the center of the town but quiet and out of the main tourist paths. The daily cleaning service was a great touch. Overall highly recommend for any stays in Oia or santorini in general!
