Erato was a wonderful place to stay while in Santorini, location is a little further out of Fira (15-20 minute walk) but this was no issue for us as we are young travellers who walk for hours most days. The pool was great and had some shade which was appreciated in the hot weather.
And staff were extremely accommodating! They were more than happy to book us tours/atv rental (highly recommend) so that we were able to see a lot of the island. The kitchenette in the room was quite minimal, we did not do any cooking however because it's easy to eat cheap in Santorini!
