We spent five nights at Sonia a Julio's place and had the best time. The flat is spacious, clean with a great collection of art and personal touches. Importantly, the beds were also very comforfable. Roma Norte is a beautiful, leafy and quiet area with many great bars and restaurants and provides the perfect base to see the rest of Mexico City. Communication with Sonia and Julio was quick and efficient and they even let us check out late. Overall, I would whole heartedly recommend staying here. Thanks for having us!
