Josue's place is in a great location near Parque de Mexico, Insurgentes, and Nuevo Leon. The location allows for easy access to all of Condesa, Roma, and Napoles. There is great food and coffee in every direction.
The best part of about staying at Josue's place is Josue. The best host I've had in Mexico City, and I've stayed at a lot of places since Aug '18. Josue noticed I wasn't feeling great when I arrived and made sure that I had tea and ginger immediately. He went out of his way to make me feel welcome on day one. The bed is also super comfortable, so there's that too.
If you're looking at this place go ahead and book it. You won't regret it.
