Recently renovated apartment on the 3dr floor of a renovated building, everything feels new, clean and tasteful. Highlight is the bright living room with a narrow balcony with absolutely astonishing view above the city skylines with and angled river view - you could spend hours just looking outside! Fully stocked with all you'd need for a stay; WiFi is working fine, washer/dryer too.
The host - Claudia - is a very friendly and motivated person, great communicator; she spent considerable time with us going over the map of the city, marking places for us, restaurants, transportation points - that was a very helpful introduction.
The location of the apartment is perfect: on a quiet pedestrian street but really close (1/2 a block) to a wider unrestricted street. No street noise at night. Oporto is very hilly, and this location is in a sweet spot between the river promenade and, say, train station. Btw, if you are coming by car, my advice - park at Parque de Estacionamento das Cardosas near the train station: multilevel underground parking with plenty of spaces on lower levels, and parking spaces are generous; you have to see attendants to pay daily 20eur rate rather than higher per-hour via pay machine, which is very convenient since you could go in and out as often as needed. The apartment is within 10 min walking (downhill).
The building and the apartment entries are key-less - another convenience.
Overall, a great place running by a wonderful host. Thank you, Claudia!
