I booked a room on the spanish site que hoteles.com which was a much cheaper rate for bed and breakfast than any of the usual booking sites (agoda, hotel.com etc)
Of all NH Collection I visited this is my least favorite. The hotel is certainly not 5 stars, the breakfast is average and the staff not very friendly nor helpful. Or room wasn’t that clean either.
Sehr zentral gelegen, die Museen Prado, Reina Sophia und Thyssen sind schnell zu erreichen und trotzdem ruhig mal und angenehm. Das Frühstück ist super.
