Marta was a very communicative host. Arrival and entry to the building was easy and the place was clean. Internet also worked well. As others have said, the Frida Kahlo suite is very small--two people (a couple) is definitely the max. Other drawbacks included pretty smelly drain(s) that caused a sewage smell to periodically waft through the apartment (found in much of Mexico city, to be fair); and very regular planes passing loudly over the apartment. I had to use ear plugs to sleep every night, which I hadn't expected since the neighborhood is advertised to be quiet.
