We loved staying in Mariví Y Roberto's apartment. We were 4 friends traveling together and stayed in the apartment for a week. We loved the style, the windows and patio, and incredible near 360 degree views from the second floor - spectacular!!!
Mariví was very responsive to any questions that I asked her, usually responding within an hour or two.
The location is fantastic for seeing all the sights of the historic center (within blocks and easy walking distance of the Zocolo, Palacio Nacional, Palacio de Belles Artes, Parque Alameda, Mercado San Juan, and numerous awesome museums and restaurants) and also great for public transportation access to other parts of the city. We took the metrobus from the airport to the apartment and walked or took metrobus or the subway to get all over town.
A few things to note:
-being in the historic center, there is the hustle and bustle of city noise much of the day and night (it didn't bother us, but want folks to know)
-we stayed for a week and ate a number of meals at home - the kitchen is stocked with a few basics for cooking but not much (there's plenty of good eating out options nearby though)
-in the winter the apartment can get chilly (especially the upstairs, since it's mostly windows), but there are two heaters in the closet
-there is an elevator that takes you to the 6th floor, but it doesn't always work. on days it does work you have to walk up the last two floors to access the apartment, but on the days it doesn't work you have to walk up all the stairs (a good workout, but given that you're already at ~7,200 ft/2,200 meters this is something that folks with mobility or health issues should be aware of).
