I stayed at Maru and Luis' apartment in Anzures for 10 weeks this summer and highly recommend it for short or long term travel. The apartment is very spacious and livable and is right on the edge of Polanco so you can walk to restaurants, jog through the park, or check out Chapultepec Castle, all in a walkable and safe neighborhood. Anzures is very central, so you can take cheap Ubers walk around or take cheap Ubers to other cool parts of the city. Maru and Luis are very friendly and helpful if you ever need anything. I would definitely stay there again.
