I spend two nights in the villa with my parents after a week in Crete. We absolutely loved the views, a great terrace and cosy lounge area. It is indeed super close to Imerovigli, but you need to keep in mind the 15 hike to the city. So if you're not very sporty, a car is an absolute must.
Besides that, we enjoyed our time in Santorini and would indeed recommend to all my friends to stay with Margarita. Thank you both for making our stay as comfy as possible :)
