HIGHLY HIGHLY RECOMMEND!!
Hugo's place is perfect for (female) solo travelers. The apartment is very immaculate, with special touch of books and art and is located within 5-10 mins walk from major hotels , restaurants, museums and the park is literally across the street. There's security at the entrance of the building and it's usually quite once you are inside!
The area is very safe, just use common sense and you'll be fine. Police presence is felt the moment you go outside and the residents are very warm people! I made a last minute decision to visit CDMX and Hugo was more than accommodating with my late arrival by providing quick responses and recommendations. It felt like home and I would definitely return again.
