Lovely large place with private outdoor area to give sense of space and openness. We loved our trip to Porto and Sonia's place was the icing on the cake. Clean, tidy, well kept throughout including the flowers in the garden. Weather was unusually poor when we went so we didnt try the outdoor plunge pool/tub. Very well located near the edge of the main area, close to the Metro but we often walked into town. We recommend getting everywhere by public trans and getting the 3 day pass at the tourist information at the airport rather than the long queues at the metro terminal...Definitely go to the main beach (Matosinhos) and get some surfing lessons from the main surfshop!
