5 out of 5 we would give for Mario.
He was really helpful and even made an app for all the new Porto-Lovers. When we had some question or wanted to have some restaurant recommendations, Mario answered really quickly with nice local tipps.
The check-in process didn’t take time and was not complicated at all. A nice and clean flat welcomed us. However, the only negative part was the mattress. The middle part was too soft for two person.
But all in all we would love to come back again!
