Our stay in Porto was amazing, which was most of all because of Mafalda. Her hospitable and gentle nature are characteristics, which make your stay there extraordinairy comfortable. Not to say, you kind of feel like home. Whatever you need or want to know, she'll tell you. She had a lot of work to do while we were in Porto, but she still took her time to show us some good locations, shops and restaurants.
Whenever you want to See Porto, go and stay with Mafalda :)
