This is a great apartment, we had a wonderful stay! It’s really stylishly decorated, newly renovated and clean. Check in and check out are super easy. It’s located in the city but on a quiet street, which was perfect because we could walk to everything easily but also had quiet sleeps. They also had really good food recommendations in a booklet they left in the apartment as well as a list of activities and museums we found helpful. Highly recommend Dario’s apartment if you’re visiting Porto!
