The place is amazing. In the heart of Fira, so everything is walkable to all the bars/clubs/restaurants in Fira Center. The design of the place is very cool. The sunrise in the morning was incredible. The jacuzzi/hot-tub was amazing. Takis was a great communicator - any questions we had were resolved ASAP, as well as setting up airport transfers, car rentals, catamaran cruises, etc. Both he and his wife were super communicative.
FYI, there's quite a bit of stairs, which is the norm in Santorini, but just be aware that if you have knee/leg/stamina issues, just be prepared to climb up and down a lot. That being said, Takis had a porter bring our luggage up and down so we wouldn't have to do it ourselves.
Overall an 11/10 experience at this airbnb.
