We had a wonderful stay in Porto at Filipe's apartment. It was immaculately clean and very well appointed with great views from the balcony. The location was ideal, being only a short walk from most of the sites and near local shops and amenities.
Filipe was a fantastic host and provided a very useful brochure and walking tour guide to us. He also speaks extremely good English and was willing to help us as much as was necessary.
All in all, a great trip and I would definitely recommend staying here.
