We had three lovely days in Porto. The flat is located nearby the central Sao Bento railway and metro station, just 5min walking distance. The flat has everything one needs, the kitchen is well equipped and there is a washing machine, iron and a small balcony to hang up clothes. It's an old building with wooden floors and a central staircase to several Airbnb flats, so sometimes it can be noisy when guests leave or come back. Mariana responded quickly and gave us all the information we needed. Check-in and checkout were fine, the door to the building has a number lock and outside each flat there is a keybox, Mariana gave us the codes beforehand. I can recommend this flat to anyone who wants to spend some days in Porto.
