Maria is always very friendly responsive. She responded every time within minutes. She arranged for a taxi in the middle of the night from the airport for reasonable fee. She also arranged a person to guide us from Oia bus stop to her place.
The location is awesome, right below the two blue-dome churches with great views. The room was small but enough for two of us.
Downside: the door lock needs to be fixed. it is very hard to open from inside. there was no amenity provided. bring your soap etc. A doormat is needed because floor was dusty
