Amazing location!!!! I mean you are near all the cool stuff in Porto. Excellent! The apartment is very spacious as well and has pretty much all you need. I highly recommend it. I will definitely try to stay there again when I go back to Porto. You can walk everywhere in town basically, and even Gaia, is right next to the bridge.
Just a note about parking. If you can, do not drive there. It is super hectic just to even get there. To park, the best place is a private lot under the square close to the apartment. The trick is, if you will stay longer than 24hrs, make sure you ask for a prepaid ticket. I didn’t know that and well, I almost wind up paying more for parking than for the Airbnb itself.
