I stayed at this unit for 2 weeks and quite liked it. Fernando was the perfect host - he was attentive, made sure I was comfortable, and provided a thorough list of what to do in Mexico City. The apartment itself is in a great location and a short walk from many restaurants and bars in Polanco, and the amount of space is perfect for 2 people.

Pro tips:
1) Have a chat with Jorge, the doorman. He is the kindest man.
2) Passion fruit (maracuya) juice from Ojo de Agua down the street is a MUST. Salads are quite nice too.
3) The Cupcake Project is a block away... need I say more?
4) Don't be fooled by the brisk weater in MXC, the sun is quite strong. If it dares to come out, play with the blinds to avoid the apartment heating too much, or, if its too cold for you, open them a little more.
