The flat is located in the very centre of the city, close to the train station, bars, restaurants and 10 mins walk from Douro river. I don't think you can get a better location than this. The place was clean and ready upon our arrival. Antonio (host) was very polite, helpful and communicative. He explained how to get from the airport to his flat using the local metro. Once we arrived he answered all our questions and gave us a couple of suggestions on when to go out and eat the best seafood!
Overall a very pleasant and hassle free experience. Totally recommended to anyone coming to visit Porto!
