Very well located apartment, really near Fira center (5min walk) and quite easy to park a car near by. It's a quite place close to restaurants/bars.
The jacuzzi is a real must with a great view, even it is not on the Caldera (3 jacuzzis on roof shared among 3 apartments).
But be prepared to sleep in a moisty room as it is called "Cave". Humidity will depend on how much you recycle air : No window, only your door and 2 wall integrated fans can be used to dry air.
Also kitchen is poorly equiped and there is no chair or table to eat :)
Apart from those flaws, will definitly remember the jacuzzi and how easy it was to go to Fira !
