Luis is literally the best host we ever met. He gave a lot of advices, answered all the questions and was really open to help with everything needed for a comfort stay.
Pros:
+quite neighborhood located really close to the center;
+all main attractions could be reached by foot;
+supermarket and fruit store is few steps from home;
+balcony (ideal for dinner)!!!
Cons:
-no AC (I should meantion that in general it's not common for Porto flats to have AC).
-Roosters in the nearby (we slept with open window and were woken up, however if you close the window no noise will disturb you).
All in all the stay was really great and I would advice Luis' apartment.
