This studio is such a perfect place to stay in the Centro Histórico, and a good launching point for Teotihuacan as well, as it's close(ish) to the Estación del Norte bus station. Beautifully furnished, so cozy, well equipped with kitchen essentials, and I can't say enough amazing things about that rooftop. It was basically an extension of the studio for us as we spent 50% of our time up there ;)
The apartment has a doorman 24/7 so it's very secure, although we did notice streets were for the most part empty at night. We were informed that the Centro can be a bit iffy after dark (as in a lot of major cities), so would recommend taking (very cheap) Ubers or taxis from designated taxi stands at night. But during the day, it's a super easy walk to all the major sites such as the Zócalo and Palacio de Bellas Artes. Thanks for such a wonderful stay!
