I always like staying in W hotels when I can (normally dependent on price). The W Mexico City is situated in a very nice neighbourhood, where a number of other large hotel chain hotels are also located. In regard to the hotel - as you would expect from a W - very fashionable, with a nice bar/lounge area - called 'The Whiskey'. Unfortunately we could make the full benefit of the bar, as we arrived when the elections were on so only had two hours when we could buy alcohol throughout our stay in Mexico City.
The hotel room was very large and it was quite a novelty having a hammock in the bathroom. Overall very comfortable and spacious rooms. The hotel staff were fantastic and the concierge provided some fantastic restaurant recommendations and helped organise a guided tour for us to Teotihuacan.
The only slightly negative thing that I can say about our stay was that the jacuzzi and sauna were not operational during our stay. We reported the issue to the staff who said that they hoped it would be up and running 'soon'. However, I would definitely stay in this hotel again if I visited Mexico City again.
