The view and the charm. This is a perfect place to englobe the magic of Santorini. You will not be disappointed. Yes, for people with low mobility the amount of stairs will be definitely a challenge but if you can deal with the stairs you are in for a treat.
This is by far the most impressive airbnb that I've ever stayed in, so romantic and the view is to die for.
John is a great host. Book it and book it fast!!!
