Christine truly could not have been a better host. Since the day I booked the Airbnb, she was beyond helpful with providing recommendations and was more than accommodating when we arrived to check-in at 11:30pm. Her housekeeper was waiting for us at the front door and gave us a full tour of the apartment, ensuring that we were all set. Also, Christine lives on the first floor of the building, which made it convenient in case we had any questions.
In terms of location, Christine's apartment was exactly what we were looking for. My friend and I wanted to be in an apartment that would enable us to have an authentic experience and allow us to immerse ourselves in the culture without feeling like tourists, and we accomplished just that. It is approximately a 20 minute walk from Roma Norte and 25-30 minutes from Polanco. If you aren't interested in walking, that's no problem at all because it's about a three dollar uber each way. As a bonus, the apartment is situated on the second floor of a beautiful building which includes a very spacious, private terrace. The terrace is also one building over/above a fantastic natural wine and mezcal bar/cafe called Cicatriz, which I would recommend to anyone visiting Mexico City. My friend and I spent most nights there and enjoyed it thoroughly. Don't worry about it being loud at night because they shut their doors at 11pm to accommodate nearby neighbors.
If you're looking for a beautiful, unique yet simple apartment, I highly recommend staying at Christine's.
