Susy is a great host, the apartment is incredibly well located, in the hear of Polanco. There is plenty to see and enjoy very close. We rented the city bikes which had a station less than a block away, and used it as a form of transport for the entire week.
The security guy was always there, he helped us with our bags and always answered our question kindly. There is plenty to do around the neighborhood, places to eat, bars to enjoy and being really close to all the main attractions that Mexico City offers.
