We enjoyed our stay at Karla's place. Karla is an excellent host. She and her sister were helpful and quick to respond to any questions we had. The apartment is well located for exploring the neighbourhood and accessing transit and going further afield in Mexico City. Lots of excellent restaurants and cafes and parks within easy walking distance. Although located on a busy street, we found the bedroom quiet for sleeping at night. Its location on the fourth floor means there are stairs to climb, which was not an issue for us, but older travellers should be aware of this.
