Barbara's place was amazing. We stayed there for 4 nights and had the whole place to ourselves. Adrianna, her housekeeper, was extremely friendly and responsive. Check-in was smooth, but I would recommend you download whatsapp since that seems to be the best way to text and call people in CDMX. Condesa is a pricier neighborhood so the restaurants and cafes weren't as cheap as I would have expected for Mexico, but still a reasonable price overall. The metro was easy to get to and ubers were always nearby. We'd definitely stay at Barbara's place again.
