We really enjoyed our stay with Fernanda. The flat was super clean and we got everything we needed for a one week long stay in Porto and even much more. Fernanda was just super kind and welcomming. You can reach her everytime and she and her son even perpared a little special map with extra insights to Porto. We highly highly recommend Nandas Apartment!
Just a little hint: We often slept with open windows and it can get a little loud on the street in front of the house in the early mornings during high traffic - nothing to worry about - we just closed the windows;)
You will have a great time with Nanda anyway!!!
