The was an excellent apartment. The location was ideal!! You could walk to just about everything a tourist would want to go to. There was no need to ride the metro (although the metro stop was about a block and a half away - Callao).
The apartment was sparkling clean! It was very comfortable. The bathroom was modern and very clean. The kitchen was tight, but typical for a European kitchen. I was able to easily cook three meals a day there! The only thing missing in the kitchen was a toaster. Every other item you could need for cooking was there.
I highly recommend this apartment for anyone going to Madrid. Great neighborhood, great building (elevators were nice), ideal location, safe, and clean.
