I had a great stay at Gabriel's place in Tlatelolco. It was a little further from the touristy spots of Roma Norte and Condessa but nothing a very cheap Uber couldn't fix. There are also some great street food restaurants within walking distance. I had the window open most nights and it was the perfect temperature in the apartment. The internet worked fast and well. Check in and check out were smooth. I would definitely stay again, he is a wonderful host.
