Gilda's place was located in a safe, non-touristy part of CDMX. There are many local restaurants and bars as well as a couple of large supermarkets within a 15 minute walk. The local OXXO is just on the corner for quick items. The metro line is only a bit over 5 minutes walk and you can quickly get into Central CDMX or Coyoacan easily. Alternatively take Uber which is generally cheap and will be much faster than the metro.
The studio is spacious for one. There is a interior patio space which you can use, but the space is overlooked by the occupants on the other floors. The main natural light comes from the interior patio space so it can be dark as the studio is in the back of the building. The kitchen has new appliances (microwave, refrigerator, washer and dryer) and the gas stove works. There is a smart TV with netflix. WiFi was 30Mb/s down, 2.4 Mb/s up but can vary. The bed is softer than I would prefer but that's me. There is a lot of wardrobe space. The bathroom is clean and hot water is ample although it might take one or two tries for the boiler to kick in. The security guard is friendly.
Gilda was very responsive with her communications, although I didn't have any issues with the place. There shouldn't be any issues with communications as her English is excellent!
If you want to experience CDMX like a local and want to avoid the tourists, this is a good area to use as a base.
