Margarita's place is very clean and nice. However, it is quite a trek to get to central Oia, but not that bad (about 20 minutes). It is close to a bus stop that will take you to Fira, Kamari Beach, etc. We enjoyed our stay, but it is slightly up a hill, so I wouldnt recommend it for elderly people. The house itself is very clean and surrounded by good restaurants (Meze Meze!). Great host, daily cleaning service.
