I enjoyed my stay at Marcela's apartment. She was always quick to respond to questions and her check-in directions were easy to follow. The apartment is small and comfortable and feels "lived in" the way Airbnbs used to (miss those days).
The bedding was comfortable, the mattress on the firmer side. Decent amount of street noise from cars at the big intersection below (there are earplugs available). The location is great. A short walk from many good cafes and restaurants, and the metro is right around the corner. The guys at the 24-hour reception were nice and made coming and going simple and safe. Overall, good place and good value. Also, try the taco stand right outside on the corner!
