This is a convenient, centrally located hotel. I didn't choose it myself, but have no complaints about it. (Nor was it anything special. Just a place to sleep and have breakfast.)
NH Hoteles seems to be a Spanish organization, with headquarters in Madrid. They say they have "256 hotels with 36,841 rooms in 19 countries in Europe, Latin America and Africa". Too bad I didn't know that before, I might have been more impressed when I stayed there, LOL.
