I stayed at Simon's listing for 5-weeks during August-September 2020 and I was very happy with my stay. The apartment is centrally located in La Condensa neighborhood of Mexico City, which is a very safe and pleasant area - filled with parks and highly walkable. The apartment is also only a 10-minute walk to nearest metro station, so it was very convenient home base to explore the rest of Mexico City. The only negative I would mention is that the room faces a rather busy street, which affords a great view of the adjacent park, but does come with a fair amount of street noise.
