There are many airbnbs in Porto but only one Paula. Her apartment occupies two floors of a building in a district of Porto that has yet to be over-run by tourists; it is about 30 minutes to the waterfront, and the walk is leisurely and gorgeous. Our bed was comfortable, the bathroom clean and the balcony is an added bonus. The wifi was reliable. Paula was very generous in her availability to us for suggestions and assistance, and we will certainly be looking to stay with her again if we return to Porto. Thank you!
