Katerina is one of the best host in my airbnb experience. Friendly, thoughtful and caring. Always checking on us how things are going. The host is very considerate to provide us with fruits and food. For transportation, there is a bus stop 2 minutes walking distance from the house. The schedule of the bus may not be available in google, so you have to go the bus stop and check the time table. Its 30 minutes to Fira, and from there you can go other places such as Oia and Kamari. You can also hike from Fira to Oia and it will only take you about 3 hours. The view is breathtaking, highly recommended! :)
