I stayed with my family for 2 nights.
We were 3 adults and 1 child (2 yo).
The flat is inside the City Towers, a condo with 24/7 reception, swimming pool and gym. The position is good, it is not in the central area of Polanco, but not far away. It is near to city market at La Europea, a nice shopping center where you can find everything you need.
The Flat has several amenities (washing machine and dryer, hair dryer) but has no air conditioning, if there is sun the apartament gets very hot!
