Manolis and Morgan truly deserve their Superhost credentials!
I have been to a number of Airbnbs hosted by Superhosts around the world and they have stood out among the other Superhosts. 
In terms of location, in my opinion it’s among the best locations you want to stay in Oia.
Walkable to main attractions in Oia such as the famous Oia sunset viewing area , Amoudi Bay , many restaurants ,shops & the bus terminal whereby you can catch buses to Fira ( & from there to other parts of Santorini, beaches etc). While it is extremely accessible, it is located at a quiet, quaint stretch. The best combination ever.
I’m particular with interior design, aesthetics & I personally love the renovation & décor of the place.
Their place looks better than the pictures. It’s very clean & you can tell it’s newly renovated & the owners have put in alot of effort, with little touches here & there.
From many windows allowing you splendid views of either the Byzantine churches to being able to see the sea/ sunset from the balcony, dining, bedroom & toilet to lovely plants, cosy lighting to plentiful power sockets ( useful for charging your gadgets wherever you are at home, not a given elsewhere )
The air-conditioning is also powerful ( you will appreciate this in summer) and a solid shower where you get ample , more importantly reliable hot or cold water.
Above all, the hosts are extremely nice , accomodating, flexible & they anticipate your needs.
They were extremely generous in allowing us an early check-in & check-out ( we were lucky there were no bookings before & after us).
Staying at their place contributed greatly to the fond, wonderful memories I have of Santorini which I will remember for a long time.
I have left abit of my heart here as I leave Santorini.
