We would highly recommend this place to anyone visiting Madrid - Vittorio was an especially accommodating and welcoming host. The apartment was - as described - exceptionally quiet (the soundproof windows doing a great job of blocking out the Malasaña noise at night!), spotless, stylish, and comfortable. It's located in a great location, close to public transportation but also tons of bars and restaurants of all kinds. You really can't go wrong, and we'd certainly stay here again if we return to Madrid.
