I stayed at Maria's Villa Kalisti for 3 days while on vacation with my husband and would highly recommend it. The place itself was picturesque and clean. It had everything we needed and there wer daily housekeeping services. The washing machine was very helpful as we were traveling with only carry-ons. There are some steps to get down to the house, but the caldera views are worth it and it is just a couple minutes walk from the main area of Oia. Maria and her associates helped arranged transportation to/from the airport, met us and carried our bags to the house at check in/out (a huge help given the stairs), and arranged a catamaran tour as well. Their local recommendations and answers to all my questions prior to our trip were super helpful since though Santorini is a heavily touristed destination, it is still a small island and not all the info is available online. The place itself was lovely but all the extra help and service from Maria and her crew made our trip much easier and better.
