Lovely flat to stay in and a short walk from the majority of sights to see. Mathieu was an attentive and responsive host, always responding shortly after we asked him a question. He had great recommendations for things to see that are less touristy and even helped me find a store where I could print a boarding pass for my flight home. The apartment itself is cozy and well appointed. The beds are comfortable and all of the amenities worked very well. Definitely recommend staying here if you are looking for a home base while you are visiting Porto.
