Editor's note
The Hilton Diagonal Mar features a rooftop pool area that guests find enjoyable, although the division of facilities between hotel guests and external paying visitors has led to significant dissatisfaction. The pool area provides a pleasant spot for relaxation, but the limited access for hotel guests and unsuitability for children detract from the overall experience.
