Konstantinos was friendly, reliable, and very helpful. He arranged rides to and from the port/airport for us and answered all our questions immediately. He provided recommendations on restaurants, markets, etc and checked in frequently to make sure we had what we needed. To top it off, he went out of his way to drive us to Fira when he were planning on taking the bus. Would definitely recommend and will definitely stay at Konstantinos’ again in Santorini.
