We enjoyed a wonderful New Years watching the fireworks over Porto from the balcony of this lovely apartment!
This apartment is centrally located in Vila Nova de Gaia, close to metro, train, and bus lines. It's a short walk to the Vila Nova de Gaia waterfront, where there are restaurants, Port wine cellars, and tourist opportunities (boat rides, tours, etc.). A slightly longer walk (or a very brief metro ride) will get you over the bridge to the Porto waterfront.
The apartment itself is clean, sports three balconies (including one with the spectacular view of both Vila Nova de Gaia and Porto), and is fully outfitted with everything you might need for a short or long stay. Four of us stayed for four nights, both eating out and cooking in the apartment, and were very comfortable. The apartment also includes a washer, which is very helpful for longer stays.
We strongly recommend this apartment - all around a great stay!
