Sergio was very accommodating and the apartment was quite nice. We enjoyed being close to many of the sights in Madrid - walking distance to many and a metro only 2 minutes away for further locations. The only problem was the noise from the street if you are sleeping on the couch was very loud. They would clean the streets at 6am and it was quite disturbing. But in the bedroom it was not so noticeable. Other than that, we had a great stay.
