This hotel exceeded our expectations. The location in central Fira was perfect. A stones throw from the hussle and bustle of the streets and shops but quiet enough to be peaceful at night (albeit with some music from nearby restaurants which is unavoidable in Fira). The view of the caldera from our private balcony was spectacular, the pool was serene and also enjoyed the same impressive views.
The included free breakfast was amazing and delicious with healthy options as well as tasty indulgences.
If I had any negatives, it would be that the pool is quite a long way down several flights of stairs, but again I can't really fault the hotel for this - it is Santorini after all. The pool was also very cold but this is quite refreshing in the hot afternoons. The toilets would benefit from having a bidet (bum gun) too but again, just nick picking at this point.
I would definitely recommend this hotel. In particular room 402!
