Pori House is in a wonderful location (far from the madding crowd), but quite difficult to reach. A person with mobility issues will have significant problems getting to/from.
We spent hours relaxing on the deck overlooking the caldera. Other than the parade of brides/models getting their photos taken, there was very little traffic near our house. Once we climbed the many steps to get up to the main street, it was incredibly crowded with all the day visitors from buses and cruise ships.
Each “apartment” is very roomy, equipped with a clothes washer and the clothes dried quickly on the rack that was provided. The Wi-Fi in one apartment works well, the other-not at all.
Maria was very responsive to emails and the people she works with (the porters, the concierge and the cleaning lady) are helpful and reliable.
We were traveling with another couple, so it was just one married couple in each apartment but there were several beds in each. (The beds are pretty firm).
We would definitely stay at Pori House again if we were to return to Oia.
