We arrived in Santorini very early, many hours before check-in. Vassilis, one of Maria's assistants, was there to help hold our bags at his house before our apartment was ready. There was a heatwave so it was very uncomfortable to walk around before check-in but the surroundings were beautiful. When we were allowed to check-in, Vassilis and his associate helped carry our bags since the apartment is set back away from the main street overlooking the volcano.
We did not meet Maria at all but she did message us about taxis that we needed. The overall apartment was beautiful and just like the pictures. However, there were no extra amenities - she only provided one water bottle in the refrigerator. The air conditioning was lovely, but the outdoor patio was so hot it was unbearable to sit outside and the floor was covered with ants. My parents sprayed for the ants each night but when we woke up they were back, covering everything. Forget about sleeping in the upstairs bedroom if it is hot, there is no air and it is an extremely tight space.
We were unable to see any of the sunsets from our porch and it was much too crowded and hot to fight for a view anywhere else. The restaurants were delicious and the location of the apartment was ideal since it was in a quiet area set back from crowds, however, you do need to fight your way up the stairs passed the blue dome since everyone stops to take pictures and rarely gets out of your way.
Overall, the stay was mediocre and we would recommend staying at a place with winds to cool off the balcony, a pool/jacuzzi and a fully established concierge.
