Margarita studios is a lovely place to stay when visiting Santorini. It's located near Perissa, which in my opinion, is the best locale if you want to get away from the bustle and cost of Fira and Oia. The studios are simple but clean, comfortable and efficient. Margarita did her best to welcome me, despite the language barrier, and George (her son) was responsive and readily available to help with any needs. He also took time to come and chat upon my arrival, and before I departed. The only drawbacks, which others have noted, are the noise of the nearby street (I'm a light sleeper, and was fine using earplugs), and the fact that it's a bit further up the road from the beach and restaurants, etc than some other places in Perissa. However, it's still an easy walk, and close to a bus stop, and if you have motorized wheels or a bicycle, it's totally fine. All in all I would recommend this place for your stay.
