My family and I just got back from a fantastic weekend in Madrid. We stayed at Fernando's lovely apartment and it worked perfectly for us. It couldn't be more central! The apartment is fully equipped and very comfortable. The only downside is the 4 flights of stairs but I used that to my advantage for some much needed exercise after eating myself into oblivion. I highly recommend churros with chocolate at Chocolateria Valor which is 20 steps next to the apartment.
