Margarita's apartment is very nice--large and comfortable with a big table in the living area that you can use to do computer or other work. The kitchen is compact and very functional and there is a good washing machine and a rack to dry clothes.
As others have noted--the street noise is LOUD. I'm used to living in a city, but there was a lot of motorcycle noise along Insurgentes late into the night. Also--like many places in Mexico, the bathroom traps don't work too well. So, there was a persistent smell in the main bathroom.
That being said, the location is excellent--a few blocks away from great restaurants, music and other attractions.
