The apartment is amazing and is full of amenities. The only issue is that it is located in one of the rowdiest streets in the center of Madrid, full of bars and clubs. If you sleep in the Mezzanine or in the sofa bed in the living room, you will find it extremely hard to fall asleep with all the noise, unless you go to bed at 6am like everyone else who is partying on the street. Since we went with kids, this was a negative point and I wished the host had shared this with me in advance. Apart from that, it is awesome.
