Oh my! That address is definetely incomplete, you are missing the basic part, the name of the Street, Square, Avenue,....whatever it is! But if what you are looking for are hotels nearby, knowing the postal code would help you a lot, postal codes in the city of Madrid look something like this: 280XX (28XXX if they're not from downtown).
Good luck!
BTW, MMan, you should name some of Madrid's streets, I love some of the funny names you give them, I can foresee one called "Calle Escalerilla de Piedra de MadridMan" in your honour in the future....
