We had a wonderful stay in Ricardo's House. Which was clean and has a very good WiFi connection. It's very good located at a little place with cafes and bars, nice view to the old tram line 1 from the balcony. Even if we wanted to exploring Porto we used the "Escadas do Monte dos Judeus" three sets of escalators to go up to the higher part of the city.
Ricardo was a great host and was available for anything we needed.
