A very spacious and quiet, somewhat older beach house in a very nice small town close to Porto with excellent restaurants at the seafront and nice beaches. The house is not luxurious, but has everything you need for a longer stay with a larger family as people actually live(d) there. Every room has excellent sea views, artworks and a balcony on each floor.
An uber taxi to Porto is under 20 euros, to the airport is under 30 euros.
There are very nice wooden walkways accross the sand dunes that stretch for several kilolmeters to both north and south, there are also bicycle paths that go all the way to Porto city.
Half an hour to the south by car head for the Castelo da Santa Maria Da Feira which hosts mediaviel feasts in August.
Aguda beach has a small natural swimming spot behind the breakwater which is safe for children to swim.
For breakfast head to Bakery Vila Maria, for lunch go to Chez Maurice and for diner go to Restaurante Zizi all within walking distance. Also worth visiting is the nearby small aquarium and fishing museum.
In short a place to recommend!
