We were a group of nine friends travelling around Portugal. We have stopped at Adriano's place for two nights. The house was amazing! Very big, clean, with all stuff we needed. I would definitely recommend that place to anyone visiting Porto. There is a metro station nearby and 3-4 stations to the city centre. You can also take a walk and it's about 30 minutes by walking in a normal pace to city centre. Host and his brother gave us all needed information about the city, where to go, what to see etc.
