We never met Maria, however she was very quick to reply and helped us out with a very last minute booking, since we lost a previous booking and were in dire need. The airbnb was clean, the jacuzzi was very nice and the view was beautiful.
The space was perfect for my family and was a perfect place to host. It might be a little tight with 9 people, but I respect that this Airbnb allows such a large group and it is a great value with a group right in Oia with those views.
Photos do need to be updated however. On the positive side, you have more outdoor space than the pictures show. There is no wall or gate separating the neighbor which we believed to be a church, so all of that space is yours. On the negative side, there is a grey "unpainted" building on the other side with garbage that some may argue could impede their view a bit. It did not really bother us though, my son was fascinated by the cats that were living there.
That being said, we were overall very happy. Great space and great location. It was a short walk from where we parked our car at the post office, and close to all the shops. We were right where all the other tourists taking pictures wanted to be.
