The apartment is "charming" and clean. Be ready for a little stair climbing if you don't take the elevator - or just one flight if you use the elevator. My wife liked to call the shower the "phone booth" as it was small by American standards and not built for a 6ft frame like me - if you drop something you will need to open the doors in order to bend down and get it. There are not any English channels on the tv, so if visiting, the evening news can be hard to digest if not fluent in Spanish. There is wi-fi, but seems limited to the main room and kept losing it in the bedroom. You will need to be cautious on the showers, as it appears to be about an 8gal water heater and ran out of hot water on us after doing dishes and then jumping in the shower - but we learned to adjust. The location is fantastic - you're in the middle of Puerta del Sol and everything is "just around the corner" so you never have to go far to find good food, the metro, bars, etc. Lots of interesting sights on the Plaza nearby - day and night. Although it is touted as a "quiet" apartment, there were a few nights where you could hear some of the crowds outside on the streets getting loud and the elevator being used.
