Irazema will be with you every step of the way. There is mention of access to the apartment by lockbox, but I honestly don't see how or where such a lock box is.
The best things about this apartment is the cleanliness and the location. There is an organic food store about 1.5 blocks away and this apartment is really right in the heart of the best of Roma Norte.
The photos do seem to exaggerate how large the apartment is, but it's definitely big enough for two people.
The building feels a bit like an institutional compound dormitory versus a residential apartment and you can hear EVERYTHING from ALL the neighbors (flushing toilets, coughing, sneezing, conversations, Friday night fun...)
But for its location and cleanliness and thoughtful guest-oriented touches, it's definitely worth considering as one of your top choices.
Thank you, Irazema!
