In a word, outstanding. From the moment we arrived, Walter was a pleasure at check-in. He was kind enough to help us with our bags up to the top floor and presented us with a complimentary bottle of delicious local wine from the Douro wine region. He also briefly shared some local history and other tips that we might find useful in informing our itinerary, and recommended some local eateries, which were also printed out for us. The apartment itself is stunning, modern and stylish but very cozy and welcoming, and the views down to the Douro river and across to Gaia and the port wine cellars there are practically worth the price alone. No TV, but you will want to do nothing but stare out the windows or sit on the balcony with a glass of wine whenever you're home anyway. The location is also top notch, on a quiet residential street, but a short walk from many of the main attractions, including Clérigos Tower and the riverfront/downtown area, as well as plenty of great eateries nearby and good proximity to the metro. Porto becomes pretty hilly almost immediately after you move away from the waterfront area, and the apartment is on a street that is no exception to this rule, but you will come to appreciate how relatively close to the river/downtown it is and the climbing it saves you over the course of your trip. Of course, as noted above, the apartment itself is on the top floor (4th, I believe), with no elevator, but unless that's a major con for you, do not hesitate to stay with Ana and Filomena. We had wonderful, full days in Porto, despite some rainy weather, and in the evenings we were always thrilled to be headed back home to recharge in this wonderful apartment. Thank you Ana, Filomena, and Walter!
