We had a great stay at Margarita's apartment. Her friend Moritz met us on arrival and was very friendly, providing us with a lot of information on the house and suggested many places to eat and drink. The apartment was spacious, clean and very comfortable. Modern and nicely decorated, really making us feel at home. Fully equipped kitchen, nice big dining table, two bathrooms and even a washing machine. Lots of room for the four of us. It is located in a great spot, within walking distance of a pedestrian street filled with bars, restaurants and shops. A big shopping centre right across the street also. Close to public transport, with the bus platform outside the front door. We ended up walking to the historical centre (took us about 45 minutes) but we found this a great way to see the city and found great local markets along the way.
Communication with Margarita was excellent, even when we had a little problem with the hot water she sent Moritz over straight away to fix it.
I would definitely recommend this apartment to anyone looking to stay in Mexico City. Great location and beautiful apartment with a lovely host.
