Four nights at the end of our trip to Spain and Morocco, that could hardly have been better. Prepaid rate made the stay very reasonable, and our room and bath were perfect for us. The floor to ceiling, shuttered doors allowed us fresh air and complete control of our room temperature (Nov.) and security. The Plaza Mayor and Palace to the west and the Prado to the east, in the midst of an interesting neighborhood was exactly what we look for. Before our trip, I called on (phone and email) the concierge to help me discover and obtain forms from Iberia Airlines that the airline reps in the US said didn't exist (to use an oxygen concentrator on flights) -- not your run of the mill query. He found the form and forwarded it just before we departed the US. He also advised on booking pre-paid train tickets (not turning me over to a travel agent), and advised on the location of the Hertz drop off at Atocha Station at the end of our driving trip. These queries involved multiple, lengthy emails, over a couple of weeks. All for a future guest who hadn't checked in. This is a remarkable level of professionalism and commitment. This speaks highly of the NH Collection hotels (which I used in Leon and Zaragoza -- separate reviews).
