I am an art historian and come to CDMX every year to tour private, VIP groups (small groups). I choose Hyatt Regency Hotel, Polanco due to its 1) open, airy feeling inside public spaces; 2) airy, spacious bedrooms; and 3) gym equipment. If you are claustrophobic and/or must exercise every day, this is the perfect hotel for you to stay at. And - a fourth characteristic of Hyatt Regency is that it is located in the best, green, non-chaotic area of Mexico City. The restaurant scene is dynamic and Lincoln Park at the center of Polanco is like being in the countryside. This is the hotel that my guests and I prefer in all of Mexico City because it is also centrally located with the best museum, cultural sites around it!
