We loved staying here, Filipe really goes out of his way to ensure we had the best possible holiday, including fresh fruit, drinks and bread plus beach gear and toys as soon as we arrived.
The area is an authentic Portuguese suburb, with great local shops, family run mini-mart and excellent cafe/bakery. It's worth exploring in its own right, with few foreign tourists around and reasonable prices.
We generally headed into Porto in the mornings and relaxed at the apartment and Miramar beaches / cafes in the late afternoons.
The local beaches are stunning and child friendly, especially around the breath-taking Chapel on the rock "Capela do Senhor da Pedra" leading to a large park with impressive fountains to play in and a children's play area, overlooked by laid back cafe/restaurants = perfect parent pitstop!
Extensive cycling lanes and boardwalks run throughout the beachfront and dunes, worth investigating bike hire or rollerskating!
There are plenty of restaurant choices around - highly recommend visiting the old fishing village of Aguda nearby or Afurada on the river Douro.
