The location is in the middle of everything! It’s a little hard to get to with luggage (but that’s just what you should expect with Santorini! It’s hilly and it was built with winding walking paths to keep pirates confused) - Katerina is not the owner, but I think she’s related to the couple that owns the place - the couple is older and they speak 0 English, so you’ll get the true Greek experience which I thoroughly appreciated (think Sisterhood of the Traveling Pants movie experience haha) … and the winding roads are actually pretty easy once you get your bearings - I barely needed Google Maps after walking there the first time with my luggage - it’s just mostly up hill and you have to carry your luggage up a half flight of stairs through a skinny entry way - but again, it’s what you should expect of visiting Santorini :) the couple will watch your luggage for you if you want to hang around Santorini for a bit after check-out, too!
My only complaint is that Katerina is a little tricky to get a hold of before booking to ask about things like early check-in/luggage stowage/taxi service.
