Arriving in Oporto, we were instantly welcomed by Igor who informed us on what there was to see in this wonderful city. You probably need two or three days to visit it but we were glad to spend 4 and practically ending up each day at one of the city beaches (take a taxi or your car). "Pro": very central location, clean and bright apartment, friendly, helpful & flexibel owners, ... Perhaps one "Con": the cooking area is not so big but big enough to make a light lunch (but do not forget: Portugal serves great food at very reasonable prices, ask Igor for a list of restaurants!).
