Marcos's apartment is spacious, light filled and comfortable. We found it true to the photos and description provided. It was very clean and had nice touches like plenty of coffee and teas to get us started in the morning or to wind down at night and good kitchenware if you want to cook. We found it to be quiet for sleeping - the traffic is minimal during the night.
The location was good for us as we like to walk. So we did walk to the museums in Chapultapec Park and also to Roma Norte. There is a Sitio Taxi at the corner which one can call or contact through Whatsapp. We only used them to take us back to the airport, but they were very nice and came right on time. The nearest Metro stop is about a 8-10 minute walk away. There are plenty of restaurants and cafes close by.
