We enjoyed our stay at Paula's apartment a lot. We were welcomed very friendly, although we arrived quite late. The view is amazing, you could see the sea from the balcony. You can also easily walk to the beach, the supermarket and the bakery. It is also very well equipped, both in the kitchen and the bathroom. We stayed there as a family of 5 and still had a lot of space.
The connection to Porto City Centre was good at all times. We would definately recommend staying there during your Porto trip.
