We only have a one-bedroom apartment in Madrid, so we rented Carlos' place, so that my parents could be with us for the Christmas holidays, but have their own space. It was the perfect location and the flat was spotless and equipped with everything you could need. Lots of little details like umbrellas, wine, crisps, biscuits and other extras all provided. Although bang in the centre it was very quiet at night. Carlos was really communicative. Highly recommend.
