I stayed in Alfonso's apartment for 2 months and I can say it is one of the better places I've stayed in CDMX. The location is perfect, on the quiet end of Zona Rosa, 2 min walk to the subway, 7 minutes to the Metrobus, 5 min to Roma Norte, and 7 min to Chapultepec. The apartment itself is quite large and spacious with one full bathroom and an en suite in the living room. It is actually very bright as the morning sun shines in through the large glass windows. Since it's pretty high up you can open the windows without many mosquitos to get some fresh air. The apartment is fully stocked with everything you need for a long or short stay. I don't know what the last reviewer was talking about or if he just lied and wrote a bad review on purpose but everything worked without any problems. Alfonso was a great host, super attentive, and responded quickly to any questions or issues. Overall the apartment is relatively quiet for CDMX (can't get zero noise in CDMX) with respectful neighbors and no annoying barking dogs in the building. I will definitely stay here again!
