Fernando & Verónica's apartment is a really great place to stay in Madrid. It is very central, within easy walking distance of many of the main sights, and also just a 5 min walk to the nearest metro if you are wanting to go further afield. It is located on a lovely square with a number of cafes/bars/restaurants, meaning it's not far to go for a quick refreshment. The apartment itself is very spacious, much larger than it looks on the photos.
