Carlos's place is an excellent base for a few days exploring Porto. It is conveniently located close to a main commercial street with easy access from the airport. There are some good cafés and restaurants in the area which let you escape the main tourist circuit, and Carlos was very helpful in recommending the best of these. It was very easy and pleasant to walk to the city centre and the main sights, and good exercise to walk back up the hill after! Carlos was understanding when I had a delay arriving at the appartment, and he gave a lot of useful tips for sightseeing. A pleasant and good-value accommodation option!
