Lis' place is well situated in Hipodromo. You're a couple minutes from Parque Mexico and not too far from major streets with lots to do. It was also extremely affordable, definitely the cheapest AirBnB that I've stayed in.
However, with that affordability comes an unfortunate trade-off. We found several gaps in the walls, which made it easy for pests to come in. We dealt with everything from small ants to big spiders and cockroaches. They typically came in after we showered. This resulted in a couple nights of really bad sleep for my partner and I, because we were concerned about what bugs could be on the floor (or in the bathroom) when we walked around late at night.
