Luis is the most understanding host ever. One of our friends took the key by mistake and he was very patient about the situation and trusted us to post us the key. The house was so clean and the view from the living room was so calming and peaceful. The location of the apartment was a 10-15 minutes to all the hustle and bustle and it was the perfect retreat for us when we were in Porto. Definitely recommend his place to anyone visiting Porto. It was lovely to meet his family as well! :)
