We have no hesitation in recommending 3Daughters. The hosts were very responsive and helpful when our flight was delayed. Great location, 5-10 minutes walking to all the main Fira attractions but far enough ‘down the hill’ (away from the caldera) to be outside the crowded zone. The place was very clean and supplied. The round bed turned out to be spacious for 2 adults and comfortable. A few notes: we were 3 people (retried couple + adult daughter). I think the unit would feel crowded with a fourth adult (but there are 4 sleeping spots: the round bed + 2 sofas). Also note no toaster or microwave. Wi-Fi was spotty and hot water unpredictable at times.
Overall - great value, great hosts, great location and we would stay there again.
