Fanis' place is amazing. It is centrally located in Thira within walking distance to anything you could need: restaurants, transportation, nightlife, etc. and yet is far enough away that you can escape the busy streets.
The pool is amazing and provided the necessary cool-off after our trips to Thira and the beautiful beaches of Santorini (yes, there are beaches and they're awesome).
The place also has an upper deck which wasn't shown in the picture, but has the most amazing views of Santorini.
Fanis, was very helpful and communicative. You are in great hands and this is an amazing place.
