We had a fantastic stay in the apartment which was immaculately presented, very comfortable and in a fantastic central location. It isn't huge but is ideal for a couple. The terrace would be wonderful in warm weather (we visited in late November). There was some noise from the street in the early hours (the street is full of restaurants and bars) but we expected this and prepared for it with earplugs. It wasn't a problem and didn't impact hugely on our stay and the pay off of being within walking distance of all the main central sights in Madrid more than mde up for it. Unless we were extremely careful with the direction of the shower head, the shower flooded the bathroom (which is not a wet room) so I had to mop the floor several times during our stay. The only other downside to the stay was that there was building work going on in a adjacent apartment which we weren't warned of in advance of our visit, so we were disturbed by drilling and banging at several points during the holiday. This is the only reason we have given four instead of five stars. I don't know how long the work is due to continue or if other apartments are being renovated (our apartment seemed very recently decorated) so it would be worth checking with the owner before you book.
