I've been in Madrid for 9 months staying at 5 different apartments during that period, I have to say that Andres apartment was BY FAR the best I've been in. That's because the ceiling is very high and it has two huge windows (with balcony), so the place is flooded with an amazing natural light, it's such a pleasure to be there. Also the location is excellent, in a quiet alley in the La Latina barrio, which is the oldest of Madrid and it's full of character, historical buildings and bars. Andres was the more enthusiastic, helpful and welcoming host I've ever met. 200% recommended.
