We stayed 10 days at Herbierto's place in Colonia Napoles. Overall we had a wonderful stay and the apartment had everything we needed to live comfortably. The WiFi was fantastic (roughly 30mb down/10mb up) and allowed us to conduct work video calls and stream Netflix without a problem.
The neighborhood itself is very safe and convenient (there is a Superama within a 10min walk). If you plan on going over to Roma/Condesa during your stay, it is an easy 5-10 min Uber (~2 USD). The kitchen is well stocked with oils/salt/spices/pans - the only downside was that we did not know how to operate the oven and were unable to use it during our stay. A very minor thing for us.
Herbierto and Noell were very responsive in their communication and had someone on-site that helped us very quickly when we requested anything. Overall we were pleased with our stay and would recommend this house to others looking for a tranquil experience in CDMX - thanks Herbierto!
