With over 50 Airbnb stays over several years, this is unquestionably the worst experience I've ever had. Not only is the description of the apartment inaccurate (what is described as "stairs" leading to the bedroom, is actually a narrow ladder that leads to a hole in the bedroom floor that must be crawled through and the are no handrails to assist with this effort), but the owner has no business being on the hospitality industry.
The first morning, after I had a sleepless night after injuring my shoulder after maneuvering up the ladder to the bedroom, I notified the Manager (not the Owner) of my injury and that we could not possibly stay here any longer. He appropriately agreed to a full refund, then showed up shortly thereafter and demanded that we leave immediately. I informed him we would leave as soon as we secured alternative housing. He relented.
Several hours later he wrote requesting 100€ payment - after agreeing to a full refund! The following morning I received a message from the Owner accusing me of being "very rude" and not "leaving a cent" for the Cleaning Womam. My apology, but after a painful, sleepless night, and then being told to leave immediately, I neglected to think about tipping the Cleaning Woman.
While the thought of staying in a 500 year old house is interesting, this apartment is very small, poorly equipped (only a hot plate to cook on, the bed small and uncomfortable, nowhere to store clothing) and overpriced. Emporio is a very poor and rundown part of beautiful Santorini.
Stay at your own risk!
