We stayed at John's rental the entirety of our trip to Mexico City and it worked out like a dream! We were centrally located in the historic center of Mexico City, very close to the Zocalo and Cathedral. We were mostly out and about exploring this beautiful city, but having a wonderfully welcoming apartment to come home to and recharge in, was truly the icing to a wonderful trip. Transportation to and from the complex was extremely easy, but also do not let this deter you from walking around the neighborhood (Los Cocuyos, blessed by Anthony Bourdain, is in walking distance)! The complex is located in a rather safe neighborhood but exercising caution is always necessary when traveling abroad. Uber drivers on numerous occasions informed us that our neighborhood was safe but that a rather "seedy" neighborhood bordered us to the west? (I'm really bad with directions), but my only advice is to use common sense and you'll be fine.
The apartment itself is rather cozy (enough room for 2) and beautifully and colorfully decorated. Both of the front desk security guys we encountered during our trip were extremely friendly and helpful. And guys, i'm not one to normally hit the gym while on vacation, but this complex has a small gym open for usage with a killer view!
Overall, I definitely recommend staying at this apartment. It was clean, beautifully decorated and extremely welcoming (They welcomed us with complimentary water bottles and a wine bottle). Thank you, John!
