Let me start by saying I'd give this 10 stars if that were an option! Just an overall fantastic and special day! My husband and I are quickly becoming the two best promoters of Viator.com! Arsenios greeted us at the top of the cable cars, those views! Santorini is a tender port and we were late by 20 minutes, due to the folks with ship arranged shore excursions departing first. The independents and there were lots of us, left right after. So, Arsenios wasn't concerned at all, greeted us with a big smile and quickly set about finding out what he could do to customize our time in Santorini. He listened to our needs, our limitations, etc and quickly came up with a plan. We were in a very comfortable van with a very good and careful driver so felt very secure and comfortable. Mostly, we felt lucky to have been paired with Arsenios as he is an incredibly knowledgeable person and also very charming. We saw the entire island, from end to end. He brought us to his favourite bakery and ordered snacks for us everyone spoke Greek so this was helpful!. Although he declined our offer to buy him something there, you could tell he was happy to be asked. He is very gracious and appreciative. He welcomed our many questions, patiently answering them all! This was the most amazingly special island. We learned so much from Arsenios that we just want to come back and stay for a nice visit and discover even more! Thank you Arsenios! You gave us a great experience, designed just for us! We are so very appreciative! We can't recommend this tour enough! You will not be disappointed, rather you will be thrilled you did!
