The flat is really good located. Only a few minutes walking and you reach everything what you want (city center, metro, super market...)
The stuff was really great! We became at the check-in a personalized map with insider tips of Porto. A big thank you to Miquel and Joao. There is only one point i have to find fault. The entrance door to the flat is not perfectly soundproofed so you can hear what happen at the hall. (And there are the check- in and out happens).
It's not that important because the most of the time you will be out in the city.
