The apartment is exactly as the photos show on the profile- clean and comfortable and located in a great place. We basically followed Pablo's recommendations (which he has nicely printed out for guests) and ate fantastic meals. The flat is located just opposite a school and as you step out in the evenings, you see many locals just hanging around the Malasana square. It's super to live right at the heart of the city and walkable to all the main attractions.
I would recommend that if you thinking of visiting Madrid, book the place without a second thought
