This apartment is well-located, clean, and comfortable. Unfortunately, there is not a concierge in this building - or at least I never saw one - which can make checking-in and leaving a little difficult. Most apartments in CDMX have one for this reason, and the listing description states that there is one. The problem is you need to have keys to exit the building, and if you're familiar with this part of CDMX you know that this can be tricky and in some instances dangerous. Particularly with two exit doors near a major street (Reforma) I had to go downstairs and unlock both doors, go back upstairs and leave the key, then exit the building. Ruben stated via e-mail that he hopes to resolve this issue, which will make leaving a bit easier. Overall, I was satisfied with the apartment.
