The apartment is beautifully located in Vila Nova de Gaia, just a 5 minute walk from the Gaia riverfront and 10 minute walk from the crowded Porto riverwalk.
The apartment is in a clean, quiet neighborhood with two small convenient stores/cafes just around the corner. The views of the river and of the city are even more beautiful in real life than what the photos shows. There is a nice little balcony where we drank port wine and overlooked the city on warm nights.
Definitely worth the value - and if you're worried about the walk - it's not far at all. A nice 25 minute stroll away from central Porto, or a 4 euro 10 minute uber ride away from central Porto as well.
