It's hard to overstate how convenient this location is to popular spots in the Centro Historico section of downtown Mexico City. The Palacio de Bellas Artes and the Calle Madero are literally minutes away, as are more food and bar options than I could count. The Historic Zocalo is probably a 15-20 walk right down Calle Madero (assuming you don't get distracted by all the shopping and restaurants). If you're looking to do this area by foot, Angela's place is a fantastic location for home base.
And Angela was absolutely wonderful host. She was very proactive in communicating, thoughtful, and messaged to check in on us during our stay to see if we needed anything. I would recommend booking a stay with her any time. We're already looking forward to our next visit!
