Margaritas place was as described, everything was sparking clean, beautifully put together cave house. The hike up the house is not bad, her assistant helps with the luggage as mentioned. Oía is literally 10 min away walking which was great! Margarita has a map how to get to her house and has available transportation to and from the airport, she was an excellent host!
I loved everything about it, would def recommend her place to anyone!
I also recommend getting a quad since you get to explore the island at your own pace and is only 100 euros. If you can get an international license so you get to ride the scooter which is cheaper, rental place is nearby as well.
Margarita is great at suggesting and recommending boat tours as well.
