I had a great time at Jorge's apartment. It is small, but very well-equipped and has everything you can ask for. Everything can be done by foot, but the metro is also close, just in case. I also loved that the neighborhood is quiet and, though close to the center, not so packed with hordes of tourists. The communication has been perfect and the check-in very easy. So all in all it's simply a great place to stay and to enjoy your time in Porto.
