Maria is a wonderful, friendly hostess. The apartment is a well-equipped efficiency one floor upstairs on a very narrow street. You can unload there, but free parking is less than a 5 min walk away. This apartment is located in a quiet corner of the Afurada section of Porto, an area that was historically home to fishermen. The attachment to the sea and fishing remains strong. There are many seafood restaurants in this small area. There is a bakery within a 3 min walk from the apartment for breakfast breads and pastries, including delicious pastels de nata. There are also 2 small food markets.
It's about a 2 km walk along the river to get to the area of Gaia where the port wine lodges are located, but if you don't want to walk, Uber is a good option. Uber is also a good option for fast transportation to central Porto. Bus service is also available, but it can be rather time consuming for tourists trying to maximize their sightseeing time.
