Marcia's modern apartment is located in a historic old building with a great location, right in the heart of Mexico City's historic district. It's surrounded by stores, shops and restaurants. The building's staff greeted us warmly and showed us up to the apartment, which was even larger and nicer than in the photos. It was sparkling clean, well-equipped and very comfortable and secure. We greatly appreciated the five-gallon carafe of water. After flying for hours, we drank water to our hearts' content. The bed is very comfortable and a standing fan did a good job of cooling us off during the heat of May. We never met Marcia, but she left an excellent guide and responded promptly to our questions by email. We give Marcia and her apartment five stars.
