Lilian was extremely responsive, friendly, and was kind enough to install a lockbox in time for our stay (we arrived to Mexico very late). The wifi worked perfectly for work and for streaming netflix, and the location was within walking distance to some great neighbourhoods in the city.
Please note that it can be fairly noisy in the area (we heard loud music until late at night on a Saturday). Plumbing is also not great. But, it reflects the very fair pricing of the airbnb. Future guest may want to sort out a garrafon for water and how to properly dispose of garbage.
