I cannot put into words the spectacular stay I had at Mario's place. If I were to ever do it again (and I will), his place would always be at the top of the list. Staying at Mario's place I can personally attest experiencing all that Mexico City has to offer, starting from its beautiful and welcoming culture to its breathtaking history and mouthwatering food. Mario was extremely helpful and responded very quickly to our messages. He gave us an itinerary that worked with how long we were staying in Mexico City. There are so many minor things that Mario was extremely thoughtful and helpful with, including with getting us the absolute BEST SEATS for a ballet at the Bella Artes and a wrestling match at Arena Mexico (he was able to buy the tickets in advance and we paid him in cash in person). Security in the building is not a problem; they are there 24/7 and are very friendly and kind. We were easily able to use the metro (~5 min walk) and catch Ubers easily on the block of the apartment. Food was not a problem at all, just walk in any direction and there will be a variety of restaurants and convenient options that you will never run out on having something new to eat. Transportation to all the must-see places was less than ~20 minutes away by Uber, however, we walked back to the Airbnb and enjoyed all the sightseeing were were able to do. The apartment is equipped with a convenient elevator big enough to fit about 3 people and 3 suitcases comfortably. Staying in Mario's house is like staying in a Museum, every corner has something to take time to look at and appreciate. I can go on and on, we had the absolute best stay here at Mario's apartment. It was wonderful.
