Great location just a block away from the Old City. The apartment is in the small Chinatown district, which was full of pedestrians on the Saturday evening when we arrived. I was worried it would be noisy for sleeping, but it wasn't. There is a 24 hour concierge to give added security, although the one we spoke with had little knowledge of the neighborhood. The apartment is small but lovely and perfect for two. A third person could sleep on the futon in the tiny living room but that would definitely make the place feel cramped.
Everything was perfectly clean. Small snafus on the part of the cleaning staff left us with only one bath towel and no laundry soap but the owners remedied these omissions within hours of our reporting them. A plus, the washers and dryers are free!!
We would definitely stay here again if it is available the next time we come to CDMX.
