The castle of cheese is a great location. Literally 2 minutes from the beach. A short bus ride away from Porto along the 500 route, which is the same route the tour buses take, but a fraction of the price. Its also close to Foz, Matochinhos (which has 3 great vegetarian restaurants, a craft beer bar, and the world's best fish restaurants (I wouldn't know being vegetarian)). The local park is also worth a trip.
The house is small, but perfect for a small group. Very clean, and the host (Maria) was on hand should we have any problems (we didn't)
Looking forward to our next trip to Porto.
