I loved my stay in this place! The place is a 20 mins walk from Fira (the capital), there's also a bus stop very near-by that can take to any parts of the island.
The room was very clean and nice. You can also eat (huge) breakfast there for additional 6EUR (totally worth it). The pool outside was just amazing!!
Maria was very helpful and friendly, it's possible to arrange all kinds of services in the reception (car rent, trips to the volcano, etc.). They said that they offer transfer only from the airport, but in the end Maria took me to the airport as well. All in all, I highly recommend it to everyone who wants to avoid massive prices in Oia or Fira and want to stay in a lovely place.
