I stayed in Mariana's place for three months and had a wonderful experience--short walk from one of the entrances to Bosque de Chapultepec, even shorter walk to the Chapultepec metro station, lovely neighborhood with bakeries and restaurants (try the Panederia Rosetta window at their sister restaurant Lardo just a few blocks away), but still quiet and felt very safe. The apartment is lovely as well, high ceilings and plenty of space, though it's a bit chilly/damp feeling in the morning and evening so the space heater comes in handy. The internet doesn't work super well outside of the main bedroom, there's a little black mold in the bathroom, and the beds are very hard, but I was able to get a mattress pad for my time there and overall the experience was great. Mariana was always very responsive if the gas cut out or the water jug needed to be replaced, she is a lovely host. Another note: the kitchen is not well stocked with pans, pots, or anything to cook with, and it's only a partial freezer, so just be aware of that if you plan to cook a lot! I will say that if you're looking for something VERY quiet, this might not be ideal, as the windows don't block out the sounds of the day, night, and weekend trash bell/street musicians/tamale vendors/gas and water sellers super well, and it is right next to a very busy street. But I would absolutely stay there again, it definitely felt like home!
