This Airbnb has a great location in Roma Norte, a couple of blocks from a market and with lots of food options in walking distance. It's about a 10 min walk to Insurgentes Avenue with frequent metro service and another 3 - 4 minute walk from there to Parque Mexico, a beautiful green space. There are also supermarkets within a couple of blocks.
The unit itself is a one-bedroom unit with a washing machine, refrigerator, and kitchen area that has a kettle, toaster, and induction cooker that plugged into the wall. It was a good amount of space for a single traveler who was looking for a longer-term stay. The WiFi had excellent connectivity and I had zero problems with it throughout the time I was there. There were no issues with the shower's hot water or water pressure.
The unit is toward the back of a courtyard that multiple units share, and there may be minor noise issues from neighbors both next door and upstairs. Overall, I didn't find that to be an issue and I thought it was a great place to spend a month in Mexico City. Balasundaram was extremely responsive as a host, so a big kudos to him on that.
