We stayed for a whole week at Marco's place and we really enjoyed it. The apartment was clean, lovely decorated and we had everything we needed. The location is not very central but all important sight-seeing and activity spots are within 10 - 20 min walking distance, and for that you got a nice small garden with orange trees (which was absolutely a highlight for me!) and a grill. There are so many restaurants, taverns and bars nearby so the night life is never boring, but still it's very quiet inside the house. Grocery stores around the corner. We definitely recommend it for anyone who'd like to have a longer stay in Porto and to explore the city a little bit more.
