This apartment is perfect if you want to explore Porto. You can reach the old center in a few minutes by foot and if you want to explore further without much walking there is a bus stop just on the opposite side of the street.
The apartment itself is cozy while the rooftop-terrace is almost as big as all the rooms together. After a busy day exploring the city you can let the day come to a relaxed end here while sipping on some port wine.
