Perfectly located for those who would like to explore museums (Prado, Reina Sofia) and contemporary art galleries (commercial and not), this hotel has an efficient and very pleasant staff, always ready to help. The rooms are basically functional, but well appointed - good showers, good beds, and while small offer enough space for work if necessary, with a stylish desk light. As usual, rooms on the upper floor are better, more specifically the ones facing the botanic garden. 3 options: superior with view on 5th and 6th floor are a bit bigger and more quiet (there are 2 doors that isolate from the corridor; standard on the 8th floor (very sought after, I suppose) and standard with terrace (7th floor), which are probably the most quiet. I guess for 2 people, Superior with views is the best choice. As always with NH, the breakfast is excellent. Here, it is served in a spacious and airy room with plenty of natural light. The restaurant on the ground floor is quite pleasant as well. So all in all, a very good 4* hotel ,very conveniently located for cultural tourists and professionals. I have been returning regularly over the course of the past 6 years, and enjoy every visit. Only improvement I could suggest: the pillows!
