First of all, Caroline and Paulo are amazing hosts - they made us feel at home immediately when we arrived and provided us with fantastic tips for where to eat and what to see. Secondly, they live in a beautiful house in a nice neighborhood of Porto, away from the crowds of tourists but close enough to the city center that you can reach everything by walking. The room is beautiful and even bigger than in the pictures, nicely furnished and you have your own private bathroom. Also, everything was very clean. We definitely recommend staying with them when you are in Porto!
