Clearly the best thing about Juan Pablo's apartment is its location: it is very well situated for sites, food and drink. Juan Pablo's communication before and during my stay was impeccable. The apartment itself is very simple but perfectly adequate. The wi-fi (so important these days) was good.
Life begins early in Mexico so some mornings the neighbour had their washing machine on at 6.20am - but this does not reflect on Juan Pablo but rather on the thin walls. And maybe it's better to get started early in Mexico City like the locals as there is so much to see and do.
Everything about the apartment and area made me feel like I was really part of the area.
Ultimately I judge a place by the answer to the question "would I stay there again?". In this case the answer is: Yes, I would.
