We stayed at João's place for just one night and even though we interacted for a short time he really made us feel at home and was super helpful with his recommendations as well as all the things he has set on his apartment for the guests. The bed is super comfortable (would say the best I've had on Airbnb), the location really good, the place is very clean and well conserved. He even arranged a cab for us very early in the morning to get to the airport.

Definitively recommend if for your stay in Porto and will surely be back if I happen to be around again. Thanks!
