Once we finally got ahold of Mario everything was fine. However I told him we did not have wifi/cellular use since we were from out of the country but we would be at his place around 2. He doesn't give the exact address of his apartment so we had to ask a random bar owner to use his phone to call Mario. He said he would meet us in 40 minutes but didn't show up for 1.5 hours.

The apartment itself is great, lovely location right on the canal, spacious, had water, coffee, breakfast.
