What a place! What a stay! This place has ruined us for other Airbnb's!
Nicoletta Christina Alexandra’s communication was fanstastic throughout our stay and they were so very helpful in organising things - be it a pick up or a car hire.
We organised a pickup with our hosts and arranged a stop at the supermarket on the way there to stock up on necessities - water, beer, etc. Our hosts kindly had a six-pack of water waiting as well as tea, coffee and condiments.
There are a couple of small food shops in Oia for provisions as you need them. We found a Carrefour which was good and next to that is a meat shop for fresh meat which was great.
Captain Alex needs an hour notice to arrange a pick up but that's fine as we weren't in a hurry to get anywhere.
We just relaxed and the view was fantastic just sitting there watching the sea-world go by and yachts/boats/super-yachts mooring at the jetty in front of us. The only issue - and had nothing to do with our hosts - was the very drunken yachty who sang, shouted and howled through the night. But, we just closed the windows (double-glazed) turned on the aircon and went back to sleep. Captain Alex gave them a serve the next day and they looked green around the gills enough on the bobbing waters that it served them right!
We'd recommend organising Alex in the mornings to get you round to Amoudi Bay and then walk the steps up to Oia from there. It's more sheltered from the sun as you trek up the steps (and there's a few less of them than if you go from Ameri Bay). And then you can just wander down the Ameri steps back to the villa.
Also, if there's more than two cruise ships in the harbour then I'd not recommend going to Fira. It's a complete 'mare with the tourists filling the narrow streets. We walked back down from the Cathedral steps - which meet with the start of the cable car queue - and about 1.5 kilometres later - I jest you not - we came to the end of the queue. I reckon quite a few missed their boat that day!
Get the bus from Oia to Fira - EUR 1.60 - from the main square and then wander up through Fira to Firostefani and Imerovigli (last spots to get food/drinks) before the walk to Oia. There was a taverna on side of road about 3 kms before Oia - I wish we'd stopped in Firostefani for that souvlaki now. Just past this you can get donkeys to the old Oia church.
The walk/hike is just under 10.5km (6.5 miles) and took the four of us about four hours. Part of the path is similar to a sidewalk, parts are cobblestone and parts are a dirt path. There is a good climb in both directions but more uphills if you start at Oia.
You can find more info on the hike by googling santorinidave
All in all ours hosts were super-hosts and made the stay a completely relaxing event. Can't recommend this place enough.
