Mario's Airbnb is incredibly well located. It's right in the center of the city, and close to all nearby attractions. The apartment itself was very clean and comfortable.
Late check-in was not a problem, since he has a doorbell from which you can easily call him to his phone. We found this quite useful.
Even though we didn't personally meet him, he was available at all times through Whatsapp.
I highly recommend this place.
