This place is very stylish and worked well for my family visit to Mexico City. The 2 bathrooms ensure that guests don't feel on top of one another, and it was amazing to have an in unit washer dryer. I'd warn that (like most CDMX apartments) there can be a lot of street noise, especially since there is no AC and we kept windows open.
I felt very safe with the 24 hour guards (who were all very nice!). There are sex workers posted up outside the apartment/down the street, which makes for a slightly more colorful experience. This didn't make the area feel unsafe in any way, but possible something that people traveling with children might want to know. I'd also mention that there aren't railings on the stairs into the building which might be of concern to guests with limited mobility.
