If you will be with a vehicle, it’s a good choice in a convenient location. If not, bear in mind that Santorini is not a pedestrian-friendly place. Usually, there is no sidewalk (I mean it, zero sidewalk) so walking a short distance is quite annoying and unsafe. And there are no short distances in Santorini. So, if you are a pedestrian, prefer a location in Fira, Oia or just beside a bus stop. You will pay more, but you will save much more in transfer costs.
And the wifi, it was present but unreliable.
