Carlos's place is beautiful, central, cozy, sunny in the afternoon and comes with everything you need (including maps of the city, travel guide, tea, wine, internet and a very friendly introduction to Porto). I would highly recommend staying here, especially if you are interested in self catering as it was definitely one of the best apartments we stayed at during our time in Portugal. Clear that thought has been put into what is needed and not needed in a flat. We enjoyed the free parking around the corner as well as well the bakery downstairs.
