The stay at Villa Agas was pretty good-- 10 minute walk to Fira (city center) and plenty of bakeries and tavernas nearby for food (including one delicious Indian place, weirdly enough)! The room itself was spacious and the bathroom was fine, they even cleaned the room for us every day. The one drawback was the bed -- it was uncomfortable and you could feel the springs. My back hurt the next day after waking up. After putting down extra blankets on the bed and sleeping atop those, it was fine though. Would reccomend, especially for how expensive Santorini already is!
