I stayed at Fernanda's Airbnb with my mom for a week! The location was unbeatable. Right in the heart of Condesa, minutes walk from coffee shops, food, two lovely parks, and shopping! 20 minute walk to Roma. There was a doorman at the building, which made us feel safe and secure even coming home late in the evening.
Fernanda met us when we arrived and provided lots of recommendations, and joined us for dinner! The place was actually much bigger than it appeared on the airbnb website. Decently comfy beds, big closets, and plenty of room to spread out.
Not too noisy, but I would still recommend bringing earplugs, as the walls are a bit thin and the windows are single-pane - which I think it very typical across Mexico City. Great experience overall!
