Great place in a great part of the city with easy access to shopping, bars/restaurants, and all of the major sites in the city. Host was great about communication and accommodating a later check-in time than planned. My only complaint would be the lack of numbers inside the apartment complex which caused some confusion as their cleaning staff came into our Airbnb twice while we were staying there by mistake. Host was extremely responsive and apologetic but since the door opens into direct view of the bedroom where my girlfriend was napping at the time, it felt like an invasion of privacy, especially on the second occasion in a 3 day stay. If they could differentiate the apartments a little more clearly to avoid this, I would definitely highly recommend to anybody staying in Porto!
