We had a wonderful stay at Kerry’s place. It was clean, welcoming and secure. Kerry was a fantastic host - ask for her Mexico City manual ASAP so you can plan your trip! She was super responsive and helpful when we needed some assistance. I would 100% recommend staying here!
Note that It wasn’t necessarily the quietest at night with the windows partially open and a loud neighboring air/cooling system, but we got used to it after the first night. This is of course expected when staying in a big city!
