Let me join the chorus of cheerleaders: the place was lovely, the neighbourhood was charming, interesting, and central (to Vila do Conde; well-connected to Porto), and the hostess was friendly and responsive, even while we scarcely crossed paths.
I am a disorganised, chaotic traveler, yet everything about my stay here was so easy that I practically fell off the metro into the flat. I can't imagine returning to Porto or Vila do Conde without wanting to stay here again.
