Karla's apartment was ideal! It's very comfortable and very well equipped, and everything is new and very well kept. It's very close to many interesting sites (Condesa, Roma, Reforma, Chapultepec, etc.) so moving around isn't difficult. I would recommend to use Uber to avoid walking at night, because the street is somewhat dark, but very safe, still. If you just feel like staying indoors, the smartTV has Netflix, so you can even watch a movie or series by logging in to your account, or cook yourself a meal. Leaving the keys with the concierge is very convenient for checking in/out, too. It really makes you feel as if you're stayin in your own apartment.
