I were warmly welcomed by Aderito in their living room where he presented Porto on a map and advised me on what to visit in the town. Then, in the backyard of their house, he welcomed me in room I rent. We had to cross a path with their 2 dogs who barked on you. If you are afraid, they can make sure to hold the dogs away from you, so no worries to have : they do not bite ;-). Everything described was there and it is well located in Porto with a bus and tramway (lapa) stations at less than 10 min by foot.
