Margarita’s place is about 15-20 minute walk outside of downtown Oia. The place itself is in a very cute neighborhood/village of its own with plenty of restaurants if you want to spend a night away from the crowds of downtown. The apartment is stylish, upgraded, and comfortable. Having the AC was a must to combat the summer heat. Like some of the other reviews, the shower is without a curtain so water does tend to splash out, but this seems to be just typical in Greece.
Only challenge we really had was identifying the meeting place to get to the apartment. You meet at the Finnikia parking lot, which is down the hill from the Santorini Mou restaurant. On the way down, there’s another parking lot, which we thought was the meeting spot. You must go down past it and come to a more paved and small but crowded lot, where one of Margarita’s assistant will meet you to help with luggage to the apartment.
Other than that, was a great stay!
