Arnaldo at Borja's place was quick to respond when due to flight schedule and travel on the Metro from the airport we arrived very late. And horror of horrors the automatic check-in did not work for us. My wife was getting panicky but all's well that ends well thanks to Borja's quick responses. My advice to fellow travelers is to always get a local SIM when using Airbnb to be able to contact the host especially during problems with check-ins. Borja's place is close to everything travelers need. Nice too!
