Perfect location to visit the city centre walking and/or by metro. The apartment sticks to the description (watch your head!) and the space is really usefully optimised. The cons are related to the old building and overall dimensions: poor soundproofing, no real separation between toilet and main room (door not up to the ceiling), and quite cold (in February) in spite of the available radiator and the heating system at disposal. Perfect and nice communication and organisation. Having lived three years in the center of Madrid and back only for a few days, I can tell it’s good value for money in the capital.
