I did not have the chance to meet Juan, but I did meet Marcela (his mum) and her daughter and they both were amazing hosts. Communication with them was excellent all the time, and they were always super kind and ready to help or provide you with suggestions regarding anything. They recommended amazing places to eat and visit.
The house is in a very good location, close to public transport and restaurants.
I would defenitely come back.
Thank you for everything!
Ester
