This appartement is really centrally located and a short walk to most key places in Madrid. Also, the appartement is big, clean and the airconditioning works well.
Although the appartement has a (really small) elevator, this elevator is only accessible after a few stair cases. Hence, with our baby/stroller this was quite an issue each time. Also the water pressure in the shower was sometimes weak and suddenly became really cold/hot. Therefore, I rate this place 4 stars instead of 5.
