I would highly recommend staying at this beautiful cave house if you choose to visit Santorini. Outside of the fact that the house itself is a work of art, Kostas as a host is such a wonderful asset in making your trip the best it can possibly be. He is prompt in his response to guests throughout the booking process as well as during your visit. He contacted us a day or so prior to our check in to see how and where we would be arriving to Santorini. He was there to pick us up at the port and dropped us off at the airport when it was our time to leave for a very reasonable price. This took all the stress out of it for us and he is a great guide. Upon arrival I asked "so, do you have any good winery recommendations?" To which he responded "Of course! That is where we are going now!" We got to know each other a little better overlooking the caldera with views that literally left us speechless. Then my fiancé mentioned that he might like to go to the ruins in Akrotiri one day and Kostas took us directly there! There is checking two things off our list without even having to think about it. He waited for us to finish before taking us back to the house and showing us exactly how everything worked and describing how to walk up to the main part of Fira. The house itself is in a traditional little area just a few minutes walk from Fira (uphill most of the way, good for us out of shape Americans haha). It is possibly one of the most unique and beautiful houses we've ever stayed in, all carved out and a wonderfully simple designed space that just makes you feel elegant and relaxed at the same time. Also just maybe a 15 minute walk from the buses. The buses are cheap enough but fairly hectic ( €1.80 one way when we were there, so if you have a few people going two ways you could ask Kostas about the cost to go by car instead) He also offered to take us to the beach and gave advice on things that would be worth our time and things that might not be so worth it. He made reservations for us on a sunset cruise and was available at anytime throughout our stay for any direction we may need. We were there for four days/three nights and if it weren't for him I think we would have wasted a lot of our time trying to figure things out on our own and I'm certain our experience would not match the level of excellence it did by staying at his cave house with his expertise and generosity as a host. Can't praise this AirBnB enough.
