This is a great place to stay in an awesome part of the city. Secure building with 24 hour guard. Walking distance to lots of things, including The Angel of Independence. Awesome rooftop patio and great balcony. The only thing I would mention is that there can be a lot of street noise.... especially if you sleep with the window open (which you likely might). You are in the city after all, so it is to be expected. If you are a light sleeper, pack some earplugs.
Overall, I can't say enough good things about The Brit! Great value, amenities, and location. We would definitely stay there again.
