If I could give the location of Erika's place 10 stars, I would. It's ~5 min walking from tons of amazing coffee spots, bars, taquerias and amazing parks. It's a pleasant ~20 min walk to beautiful nearby Roma and Chapultepec Park, but we honestly could have spent our four days in a four block radius and been consistently entertained. **We were four women and felt extremely safe walking around the neighborhood late into the night.
Erika was also extremely communicative both before and during our stay. There was a small earthquake while we were there and she texted right away to check in and see if we were OK.
The only downside of the apartment was that is was a bit echo-y, and it seemed like there was another AirBnB hosting a group of loud visitors. This generally wasn't an issue for us, but something good to consider if you're looking for a restful trip where you can get lots of sleep.
