João is an excellent host. He messaged us to make sure everything was okay during our stay. The temperature was very hot for a few of the days we were in Porto, and João brought a fan over for us. The only thing that I would say was an issue was parking. If you are bringing a car the street parking is only valid for 2 hours and the nearest parking garage is at the end of the block and then right a block over...We paid 15 euros a day.
