Costas place was very nice. They helped us with everything we needed and we have no complains.
The place is like a b&b, you have your own room with your own keys.
I didn’t think the breakfast was worth the price of 7€, but that’s optional.
Everything in Mílos is a little bit far away from the famous beaches, so the best thing we did was renting a car, otherwise I don’t think we would have enjoyed as much as we did.
