Bertha's apartment is a great place to have as a base for exploring the city. It is located in a lovely area of the Condesa neighborhood and it is very quiet and safe. The apartment itself is well appointed with everything one needs and it is very comfortable and super clean. The bed in the master bedroom is super hard, so that may take some getting used to for some. Mary, who helps Bertha host and cleans the apartment (once a week) was lovely and helpful. We are a family of four (with two small children) and we had a great two-week visit, and Bertha's apartment was a perfect place for us to stay.
