Wow! What a place! The living space is as described and has both indoor and outdoor spaces. The rooftop deck was comfortable to play games and enjoy drinks in the evening, and the bed, while a little hard (which I prefer), had a great view of the plants and city. There is a small seating area inside, which we didn't use since the weather was great on our visit, as well as a well-equipped kitchen (including dishes and silverware). The refrigerator is small but has a freezer compartment big enough to hold a mostly full bag of ice (purchased at the Oxxo a few blocs away). There is plenty of storage for luggage and clothing in a closet between the bedroom and bathroom. The shower had plenty of on-demand hot water, although the drain was a bit slow. The apartment also had plenty of towels, extra blankets, soap/shampoo/body wash, and dish soap.
Public transit (train) is fairly close (10 minute walk), although if you take the Metro to the Tacubaya stop, exit the station on La Doctora for the shortest and easiest walk to the apartment. We were very turned around when we left the first exit we saw and had to walk along busy streets to get headed in the right direction. The walk to the Patriotismo stop is very easy and straightforward. We didn't spend too much time in the neighborhood and can't speak to restaurants or services in that area.
We were able to arrange to drop our luggage off with the front desk, and there was someone there 24 hours per day to let us into the building. It felt very secure. There is an elevator to the fifth floor, but you will need to climb a flight of stairs to the apartment.
We stayed here at the recommendation of friends and would certainly recommend it to anyone traveling to Mexico City who wants a more residential and quiet neighborhood with easy public transit access.
