The four of us (including two 18 year olds) had a great week's stay at the Mansion. While initially finding it was a bit challenging (we had to ask in the NST Travel office, which we realized was a 3 min walk away), it's location proved to be very convenient especially for our girls who felt free to roam and shop ;) It's on a side passage in the old village and unlike some other reviews, we didn't find the very occasional voices or luggage wheels an issue. The Mansion afforded comfortable space, we all slept well and the AC was welcome after long days of sightseeing, visiting vineyards and going to the beach. There also was no issue with the Wifi. Joanna was always promptly responsive, the space was very clean when we arrived and someone came every day to clean. Coffee and shower toiletries were replenished, and I suggested to Joanna a few minor additions to the kitchen supplies which would make it more user friendly for simple meals. As noted, the third bedroom is only accessible up a ladder, but also know that this is the only way to get up to the roof to watch the sunset. Our evening routine was to watch the sunset from the roof (which was fun because everyone around us was doing the same) and then have dinner out on the front patio. Given it was high season, Oia does get particularly over-run by tourists for the sunset and we opted to eat most lunches out and have easy dinners in. (Particularly in Oia, we recommend Roka and santorinidave.com has invaluable information about visiting the island.) If you stay at the Mansion during the high season and have a car, expect to find parking doable, but definitely a challenge. Again, we had a wonderful stay and depending on what you are looking for, the space definitely worked for us.
