If you are staying in Mexico for long term/short term, just stay at Adrina's place. Check in process was very smooth and easy to get reach out to her when issue happened. Right next to Reforma av. So basically close to everything; bus stop, cafes, bars, restaurants, shopping mall, etc. Quite and safe area even after midnight.
Oh and I was a little worried that the apartment might be dark because of pictures. It is very bright apartment with blinds (not going to bother your good night sleep)
