Carlos's place is gorgeous - it looks like it's out of architectural digest or something. The courtyard is huge and incredible and the building itself is super quiet and peaceful despite only being a stone's throw from Av. Obregón on one side and the hipster bits of Roma and Condesa the other. Carlos is super friendly and helpful. I got really sick with montezuma's revenge during my stay and he was so kind about it, offering to take me to a doctor and get me medicine etc! All in all a brilliant stay.
