The apartment checks all the boxes: it's clean, well-equipped, and well-located. All of our destinations were within walking distance.
Carolina and her team are very friendly and super responsive. They greeted us at the apartment and gave us great tips for the local restaurants. If you have a car, the parking is a real plus, since you can just leave the car in the garage for your entire stay without needing to take it out on Porto's narrow, bumpy inroads!
All in all, highly recommended.
