We stayed in Giannis' place as part of our honeymoon trip, and the apartment was just amazing. Santorini was quite busy so the location of the suites was ideal, and away from the busy areas, however, a walkable distance to them as required.
The suites also have the best view of the popular Santorini sunset from the roof terrace. Beautiful place, great and accommodating host, luxurious accomodation and an ideal location. We would highly recommend!
