Marco was helpful and sent all the needed information how to arrive to the flat, we were greeted well and the personalised "what to do" information sheet was a nice touch. The area where the flat is located is brilliant, right next to the river with cafes and restaurants on the door step. Tram No.1 or bus 500 (as well as the tour bus if your interested) stops just outside the building which takes you to the seaside of Matosinhos. The building and the flat itself is beautifully designed with all the necessary amenities, felt safe and secure. We stayed five nights and had an amazing time exploring Porto!
