We had a great stay at Luis' apartment! It's in a wonderful location, within walking distance of all the sites, as well as the river and Vila Nova de Gaia. The apartment has an awesome vibe, and we felt very comfortable. We especially loved the high ceilings, many windows, and little balconies overlooking the city. Luis was extremely gracious and accommodating. We had a late flight, and he was nice enough to meet us to let us into the apartment. He also gave us many recommendations for local restaurants and bars. We highly recommend staying at Luis' apartment!
