I absolutely loved my stay in the apartment! The view was gorgeous, waking up to the sun shining right on the bed (when you open the curtains) was a delight. The apartment is right by the Rua das Flores and just a 10min walk from the riverside. Sofia was extremely nice and I was welcomed with some fresh oranges, wine and cheese. I couldn't have asked for anything better!
Sidenote: the seagulls seem to love hanging around, earplugs are a good option if you want to sleep in! ;-)
