Our stay was great! Porto is a beautiful city and the apartment is the right places to stay. You have to walk a little to get into the city centre but you don’t need to take the train or bus- just a 10 min walk. The apartment itself is very much clean, only the bathroom is “used” (leichte Gebrauchsspuren). At night it can get a little louder, so if needed I would recommend to bring earplugs, but after one night you get used to it (normal city sounds / volume)
All in one the best stay we had on our road trip through Portugal- would absolutely recommend !
