We had a fantastic experience working with Mario and his wife in advance of our arrival, and thoroughly enjoyed our stay in their tastefully decorated, centrally located apartment. The master bedroom was very large, bright, airy, and while the 2nd bedroom was a bit small, and had no window, our adult sons found the beds to be very comfortable.
The kitchen was well stocked with everything we needed to make a complete breakfast....which was the only meal we "ate in" each day.
Our stay was over Christmas week, and as Plaza Mayor is the center on Madrid, it was like looking down on Times Square on New Years Eve every night we were there. While that might seem like a negative to some, we enjoyed our birds eye view of the festive scene. Tat said, when we wanted to go to bed, we closed the windows, and the noise was a non issue.
Overall, I would rate our experience very highly, and recommend this property as a great place to stay when in Madrid !!
