Flavia and Manuel were verynice and flexible. Manuel was in the flat to welcome us around 10pm. The next day, they let us stay in the flat as I needed to work and our flight was in the evening. The flat is in a very nice old building located in the Calle Gran Via in the heart of the city, close to bars, restaurant and shops. Metro is 2min away. I would recommend the place to anyone willing to stay in central Madrid. Internet is fast and beds confortable (even the banked bed). Very good value
