I absolutely recommend Antonio's appartement for a stay in Porto. It is very clean and well equipped, there is a lot of space and a little garden in front of which we used to take each of our meals. Antonio is a really kind host and he accepted that we left our luggage in his office right under the appartement before the check-in because we landed quite early in Porto. We used our time enjoying the beautiful view on Porto from the "Jardim do Morro" surrounding the city, which is not too far away from the appartement. The city center is only 20 min away by walk and Porto is a really beautiful city!
