This place is lovely! My family and I stayed at two different locations/properties during our time in Santorini and both were exceptional. Maria (and others) were wonderful and accommodated our needs. They arranged our transportation, transported our luggage and offered any assistance during our stay. Also, they provide daily housekeeping, that was a plus! The place easily accommodates four people. Its was clean, comfortable and in the most wonderful location -- beautiful sunset views. We would definitely recommend this place and will definitely be returning.
My only warning is: stairs. There are a lot of stairs. If you are unable to climb stairs, this might be difficult for you. However, stairs are to be expected if you are staying in Oia.
