The honest take
The St. Regis Mexico City is $695 a night with a pool, hot tub, bar, parking and pet allowance, on Paseo de la Reforma near the Angel of Independence. Casa Polanco is $1,505 with none of those facilities listed, a small boutique operation of about 102 reviews in Polanco. Casa Polanco edges it slightly on guest rating, 9.6 versus 9.4, but at more than double the price and with a shorter facility list, the St. Regis is the clear booking.
The look and the feel
Casa Polanco Hotel Boutique
Casa Polanco reads as a converted residential townhouse turned into an intimate boutique property, the kind of place with a handful of rooms, a rooftop terrace, free bikes propped by the door and a small dining room rather than a full restaurant scene. Polanco itself is leafy, moneyed, low-rise, full of art galleries and the Soumaya's silver curves a short walk off. The feel is domestic and personal rather than grand: a house with good coffee machines and balconies rather than a hotel with a lobby you're meant to be photographed in.
Right for someone who wants a small, quiet, residential-feeling stay in Polanco near the museums, and doesn't need a pool or bar on site.
The St. Regis Mexico City
The St. Regis on Reforma is the high-rise glass tower version of American luxury hotel-keeping transplanted to Mexico City, all marble lobby, chandeliers, and the signature St. Regis butler on every floor, a holdover ritual from the original New York property. Reforma outside is the wide, tree-lined boulevard with the Angel monument down the road, embassies and glass towers, a more civic and formal stretch of the city than Polanco's residential quiet. Inside there are three restaurants, two ballrooms, spa treatment rooms and a rooftop pool looking over the avenue, the kind of place built for business travel that wants a drink and a swim at the end of the day.
Right for business travellers, couples wanting a proper spa and pool, or anyone who wants the ritual of Reforma-boulevard grand hotel service without paying grand hotel prices here.
Casa Polanco gives up the pool, hot tub, bar, on-site parking and pet allowance that the St. Regis has, in exchange for a smaller, more residential Polanco setting.
The St. Regis is the more theatrically beautiful building to walk into, with its marble lobby, butler service and Reforma views, while Casa Polanco is the more charming place to actually live in for a few days, so it depends whether you want spectacle or intimacy.

“Amazing luxurious stay!”
What a wonderful stay! We were upgraded to a beautiful suite room 1001. We also used their airport transportation and Roberto was excellent but so was the other driver. When we arrived the bellmen promptly assisted us with our luggage and we were checkin. We were excited to have seen the nice upgrade (am Ambassador) and they acknowledged my status. The whole stay was magical. The King Cole Bar is a wonderful space

“Treated Like Genuinely Welcomed Guests”
The St. Regis Mexico City is an outstanding hotel, and we can't recommend it highly enough. From the moment we arrived, we were treated like genuinely welcomed guests. That began at check-in, where the team took real care with our room selection, and it continued throughout our stay — there was always someone asking whether there was anything they could do to make our visit more enjoyable. That kind of consistent, at

“Impeccable rooms, perfect service”
The St Regis has the best service of any hotel in Mexico City. The rooms are impeccable, and the security is top notch. The terrace of the restaurant is lovely for a relaxed brunch any day (or every day) of the week. Special thanks to Iliana at the front desk for her outstanding hospitality and kindness.
