Bernardo was a wonderful host and was very responsive during our visit. The location is safe and very central, especially good for first time visitors or people visiting for work. I would recommend going to the nearby Ecobici kiosk (a bike share program) on La Reforma, getting a temporary membership, and using those to get around. It's easy and there are lots of protected bike lanes on many larger streets and plenty of quieter side streets to wander around on.
