Being a guest at costa's place will be one of my best airbnb memories. We have been adopted by his family, sharing moments when we want to in his beautiful garden just in front of the sea. The flat itself is ok, everything works fine, but the location is amazing. You can enjoy an almost private beach, walking 30 seconds from your apartment, not crowded at all. Rethymnon is a pretty good city, with lots of tavernas. We have eaten at prima plora, a great romantic restaurant in front of the sea, and quite not expensive (around 10e the main dish, and the house wine is good). It's also very nice to cook at home and eat in the garden, which again is splendid. Costa has been very great with us, and made us feel at home. You can walk to the bus stop and visit also some small villages (we particularly loved the arkadi monastery).
I do recommend this place for peaceful vacation, to avoid crowded beatches.
I strongly plan to come again at this place if I go back to Crete !
