What a wonderful place. The location is absolutely perfect to explore centro histórico and is easily connected to the rest of the city on the metro. The apartment itself is extraordinarily clean and quiet.
My favorite part of this place was the uniqueness of the building. It appears that this building was heavily modified from its historic roots to become condos. They did a great job of creating unique living spaces while keeping as much of the history of the building as they could. I highly recommend staying here for a few days if you are passing through Mexico City.
