If you want a traditional, authentic stay in a beautiful neighborhood, stay at Victoria's home! The house is lovely and Victoria ensures that you will feel at home when you stay here.
Coyoacan is a neighborhood recommended to me by a friend originally from the area, and since it was my first time in Mexico City, I took up his suggestion. Victoria's home is about a 10 minute walk to the zocalo and about 15-20 minutes to the metro station. Kahlo and Trotsky museums are in walking distance, as are good restaurants and everything else you'd need. Getting to the rest of the city can take some time but I thought the neighborhood was great and I didn't mind traveling into downtown cdmx at all. I like to walk around at night and I felt perfectly fine.
Victoria also loves to prepare breakfast for her guests including fresh fruit and sometimes hot meals! It was an awesome stay and I highly recommend it!
