First of all: Bruno is a super host! He gives you a lot of recommendations, he takes the time to tell you about his beautiful city and helps you with everything. Also he speaks English very well!
The apartment was very nice and very clean. The location is good, there are a few free parking spots around the place. You can easily walk to the center of Porto, but you can also take the tram etc.
It was perfect, we would totally recommend this place, we'll come back.
