Without a doubt, Giannis is one of the best hosts I've ever stayed with in my more than 50 AirBnB experiences. Giannis went out of his way to make our stay enjoyable be it providing advice on places to go, things to eat, and even bringing us grapes and olive oil from his own orchard! Not only that, Kissamos is a perfect place to stay if you are looking for someplace a bit more laid back, authentic and off the tourist path.
Would definitely stay with Giannis again!
P.S. Giannis also has the best connection for Thyme Honey that I've come across in Crete so make sure to ask him about it!
