The apartment was impeccably clean and was as shown of the pictures. It met our expectations in terms of value for money. Security to the complex building was top notch. Regarding the neighbourhood: although it is located in the Miguel Higaldo borough, don't expect the fanciness of Polanco or even Granada even though these two "colonias" are only a few blocks away. It is a lively area where you can experience the reality of the average "chilango" life, and everyone is courteous and friendly. There is a typical market two short blocks away where you can enjoy real quality food for very little, not to mention a plethora of smalls and services (such as barber shops, hair salons, and an exceptional podologist right next door, better and more competent than anyone I found in Toronto).
Now for the so-so part. It can be noisy, especially on weekends. Dogs barking, cats in heat, and loud music. The apartment is located on the 5th floor, without an elevator, and factoring CDMX's altitude (2,725 ft above sea level), it is likely to provide you with a better cardio workout than 80 floors on a Stair Master in 20 mins than I do back home. Take that into account if you are no longer a spring chicken. And if you are averse to anything that is not like the USA or Canada, Colonia Pensil is not for you.
