Maria replied to exchanges leading up to the stay promptly and helped us arrange for a pick-up at the airport. Although we expected a taxi to be exclusively for us, we ended up in a shuttle with another two people. Still the arrangement was necessary as there's no other options to get to Oia easily.
Upon arriving a porter met and lead all four people to our arranged houses, and explained the facilities and arrangement for check out. Obviously having to be at two places at the same time meant the other two people were left out in dark whilst he opened the door for us, and then us waiting whilst he ran back to assist the others. We had some issues understanding each other and at some point there was some tension in the conversation, but finally we came to a common understanding (I think). Nonetheless the porter was also necessary as you'd not be able to find your way to the address easily otherwise, due to the windy stone paths on the hill.
Overall the house matched our expectations from the photos, we had everything we needed, the view was amazing and the area was quiet. The house was warm without using any heating, which was great as the evenings were quite chilly outside. It is close to the main path full of shops and restaurants. The bathroom is separate from the house itself, apart from having less privacy it was also quite cold having to get out of the house everytime.
