We had a wonderful stay in João's apartment. The apartment is very classy, very clean and well kept up, and superbly located. (For coffee and pastries, we highly recommend Natas D'Ouro directly across the street). Although the apartment is on a fairly busy street, inside the apartment the noise from the street was light and pleasant, never disturbing. And João is extremely helpful and kind. When we arrived into Porto airport, my suitcase did not arrive. João very kindly talked to the airline claims agent for me via telephone, and then arranged for the suitcase to be delivered the next day directly to his warehouse, so that I didn't have to wait in the apartment all the next day for it to be delivered. We also really appreciated João's flexibility on our check-out time; it really helped make our last day in Porto more enjoyable. We'll definitely contact João next time we come to Porto.
