The apartment is wonderful, very spacious and clean with nice amenities (a doorman, strong wifi, a washing machine, etc.). Juan Carlos was a wonderful host. He was very responsive to emails, and even hooked me up with a friend of his who is in an academic field adjacent to mine. Just be aware that it is not in a posh neighborhood. I had absolutely no issues and everyone in the shops, etc. was very friendly, but some travelers are more comfortable in areas that are geared toward visitors from abroad. If you want to stay in a working-class neighborhood that is very centrally located and right on the central lines of transportation (Metro Hidalgo is 500 feet away), this is a great location.
