The place was looking nice and accurate to the description. The location is good but the noise is unberable some nights. We stayed for 8 nights while working from Madrid during the day, but the lack of sleep made our stay very tiring. This is partly because of the location but also the balcony doors which were old or not properly isolated, letting in outside noise and cold and also creaking very loud.
The apartment also lacks any basic utility like dishes, forks and knives, mop, vacuum cleaner, so for a 8 night stay the apartment got pretty dirty.
I would recommend this apartment only for a few nights and if you come to Madrid to party due to location and noise.
