Dennis's place is exactly as described - beautiful, clean and unbeatable location. We checked in and checked out at odd times but Dennis made sure we had no issues. The view outside the terrace is great and just steps away from one of the main attractions of Santorini - three belles of Fira. There is a car park just next to the property. Dennis provided some great restaurants recommendations which made our trip even better.
Overall, we dont think you will get a better deal for the price in Santorini.
