We had a wonderful stay at Mario y Noelia's apartment. Located inside the 400 year old Plaza Mayor, the location could not be any better. A real treat. While initially I was disappointed that I could not reserve one of their units with a view/balcony looking out over the Plaza Mayor, I actually ended up being relieved, because we were able to enjoy the location without any noise. The apartment was so quiet! We slept great each night. The apartment is also quite large -- especially for Spain I am told. It was very clean, had all the amenities you could want (although a dryer (only have a washer) would have made it even better). The TV did not have any English stations and the Netflix didn't seem to be set up, but who the heck wants to sit around and watch TV while in Madrid? Communication with Noelia was top notch. She was responsive within minutes - met us to drop off the key and show us the apartment, shared details of the city, and arranged for taxi to the airport our last day. Excellent value - WHEN we return to Madrid, we'd certainly be happy to stay again. Thank you Noelia!!
