Great location (walking distance to Chueca, Sol, Gran Via and lots of restaurants and shops), spotless, the bed was super comfortable. The attention to detail is a real advantage: being able to have coffee in the morning, take polaroids throughout the trip and even wash your clothes all included in the price! Would definitely recommend!
p.s. could get a little noisy because of how busy the main street is - something to keep in mind for light sleepers.
