A friend and I stayed here for a whole month while we were studying abroad in Madrid. The location of the apartment is great, right by a metro stop and within walking distance of Puerta del Sol and Plaza Mayor. It is VERY small but we stayed there for a month and made it work. The beds are comfy and there’s a decent amount of storage space in the bigger bedroom. You also have your own little patio area to hang clothes which is nice. Overall a pretty decent stay in a good area.
