We just had a three day stay. There was much that we liked, and a couple things that we did not.

1. We love the location. It is in Polancas district. It's easy to walk to a wide range of restaurants and stores.
2. The hotel is very intimate with just a few rooms on each floor. It is only 7 floors high. We saw many high rise hotels in Mexico City and far prefer this boutique size.
3. Breakfast was outstanding. I dislike breakfast buffets. Here, there was a menu. You got your choice of orange or grapefruit juice, a plate of chopped up fruit in a bit of yogurt with some seeds on top, a choice of a pastry, and tea or coffee. Then there was an extensive list of breakfast items, both Mexican and American. You could choose one. The chiliquiles were superb as was the French toast. It's a treat to have a hotel deliver such good breakfast food. We followed advice above, where we had breakfast and then ate a second meal during the afternoon. We skipped an evening meal.
4. Concierge service was good. I reached out well in advance and asked that Pujol be booked for us. Quintonil and Pujol are high on the list of the Top 50 Best Restaurants in the World. We got our Pujol booking. It was a short walk from the hotel. We loved it, very sophisticated modern Mexican food. We also ate at Dulce Patria in the hotel. I was skeptical but it was excellent. Again, it was sophisticated modern Mexican food though more mainstream than Pujol. There was flexibility in what we chose rather than the prix fixe at Pujol. The concierge also booked our car transfers and a private tour of Luis Baranger's 3 sites. He was the 2nd architect to win the Pritzker Architectural award. I waited too long to book the public tour so was happy that the hotel has a relationship with an architect who knew Baranger and offers private tours. It was pricey but we appreciated all that we saw including the last home that Baranger designed. He consulted with Louis Kahn on the Salk Instittute central courtyard in La Jolla. It was fun to learn about this local connection.
5. Nonalcoholic beverages along with nuts and candy in the minibar were free.
6. A selection of 7 unique soaps made by a local group of women from herbs and flowers were left in the room.

Things I didn't like so well:

1. I booked a deluxe room and was upgraded to a corner room. It had a half circle window with lots of light flooding into the room thru tree branches. However, the room was still not very spacious. It had a chair at the desk and a partial chaise along the wall. I always want a chair and stool in a room. It lacked even a comfortable chair. Further, the TV and chaise were along the same wall so there was no place in the room to sit and watch TV. The hotel was fully booked and no further upgrade was possible.
2. Internet was frustrating. My computer dropped off frequently and even when on had very slow connectivity.

I spoke to the hotel staff about both issues. The hotel is to have a renovation this summer and get all new furniture. And the concierge was planning to call their IT company.

The hotel GM, Michael Chiche, left about two months ago. The new GM is Daniel Malo.
