We have spent three days in Madrid for a short family holiday and the apartment has given us everything we need for a lovely and convenient stay. Kitchen is not too small and has all the basic things one needs to cook a meal. Bed and sofa bed are comfortable enough for a good sleep after a day out and had there been no air con in the apartment, we could not have coped with Madrid's heat in summer at nighttime. All in all, we are very pleased with the apartment's facilities and owner's service, thorough and professional. Strongly recommended and we will certainly like to rent the apartment again we are next in Madrid, either for leisure or business.
P.S. We would really like to give this a five-star experience but the climb to the top floor (fourth) is the only downside.
