Roberto was a very kind, flexible and responsive host. He also provided good information about the surrounding neighbourhoods.
An absolute plus regarding the place is how quiet it and the immediate neighbouring streets are. This, I now know, is quite rare in CDMX.
There were, however, some things that made the stay a bit unfortunate:
1. It wasn't very well cleaned when we got there, resulting in lots of spiders, a layer of dust in the wardrobes and old food burnt in some kitchenware that made them unusable for cooking in the kitchen. I think it should be noted that Roberto told me the spider problem should be taken care of properly before any future visitors come.
2. There were times that the kitchen area started smelling a lot from the gas stove. This should be looked into.
3. The apartment wasn't family-friendly in terms of being able to hang out together due to the choice of decor and layout. Very narrow couch and chairs were to low for the kitchen table.
