My husband and I spent a fantastic week at Marco's apartment.
He was extremely professional, responsive and friendly. His place was clean, spacious and exactly how it's shown in the pictures (we loved that he had a purified water dispenser). The apartment is in a great location, walkable to a variety of bars, restaurants, street food, and neighborhoods. We felt very safe there and the doormen were extremely polite and helpful.
I would highly recommend staying here to anyone visiting Mexico City, you won't be disappointed.
