We stayed for 6 nights in the apartment and had a great experience! It is very close to Coyoacan's main parks and market, where we went almost every night to people watch and eat dinner (albeit a bit further from the metro stop, but Uber was a very convenient alternative). Carlos was not available but his family were very warm and welcoming and made sure we had everything we needed. Their brown labs were also very fun to play with. The apartment itself is quite simple but had everything we needed. I would definitely recommend!
