Marijose and this apartment are both amazing. I stayed for 6 weeks and, honestly, would stay longer if it hadn't been booked.
The location is great (near stores, metro, bus, and walkable to many things), the building is lovely (24 hr security, rooftop, gym) and the apartment is a great place to call home (stylish but comfortable, every amenity you need from strong, reliable wi-fi, to a fully stocked kitchen). The thing that really makes this place stand out, however, is Marijose's hospitality; she was always quick to reply to messages, was flexible when I needed it, and even provided cleaning for my long-term stay, which was greatly appreciated.
As I said, if I could stay longer, I would; so lucky you if you're reading this and manage to find some open dates to stay here on your visit to CDMX. :)
