Just to be clear, my real rating is a 6 out of 5, but due to technical limitations this review just says 5 stars.
Alex and Nikol are incredible hosts. Before we even arrived I had ferry trouble which resulted in us arriving at 4am. Alex arranged for our transfer directly to the place and let us "camp" out in his garden so that we wouldn't be stuck in the streets with our luggage for hours.
We napped in the garden until stuff started opening, and then left the luggage behind to eat breakfast and explore the town. Meanwhile, Alex worked behind the scenes so that we could check in early and messaged me when the room was ready.
I give this long explanation just to show how hard Alex and Nikol were working on our behalf even before we officially checked in. That attention continued throughout our stay.
Alex was essentially a tour guide working on our behalf. He gave great recommendations, made reservations for us at hot spots, and was always checking in to make sure we were having a great time. Nikol baked us a homemade cake which became our daily snack for the day.
In short, Alex and Nikol are the definition of "super hosts" and I would strongly recommend anyone to stay here just to be in their care.
But the place is also immaculate. Alex and Nikol live in the top unit so it's not just an AirBnB but also their home. As such, it is maintained to a flawless level. The place was possibly the cleanest AirBnB I have ever stayed in and we loved everything about it.
I could gush for several more paragraphs, but I will just say that I personally would not consider staying anywhere else but here for my next trip to Santorini.
