Solid location if you are looking to enjoy the nightlife - the area (Malasaña) is fantastic. Its also fairly close to the center (Gran Via / Sol)with a 15-20 min walk. The flat is very “efficient in its layout”. Maybe it lacks some lighting & windows, but if you are looking to be out and about its a good place to be. The street is quite quiet as well, and the amenities are good and of good quality.
