We absolutely loved our time in Oia. Maria was very easy to get in touch with, and when I called her at the bus terminal in Oia, a porter was there to greet us and take us to the Blue Volcano in minutes. The view from the porch area overlooking the caldera is second-to-none. The room itself is fairly basic, and because we were traveling internationally, it would have been nice if there were some toiletries in the restroom. Getting to the bathroom from the room also requires stepping outside. All in all, this was a really great location for exploring beautiful Oia.
