Carla's was an amazing flat- the location could not have been better. We arrived on a Monday and left the following Sunday and walked almost everywhere in the Unesco city center. Getting lost in the Porto streets and then finding sites by serendipity is definitely the way to experience the city. And Carla's flat gives you a clean, stylish, and stunning home with a well-stocked kitchen and heavenly bed to come back to.
The views can't be captured by the photos. Go to the kitchen and stand on the narrow balcony and just watch the people go by, shopping, taking selfies, drinking coffee. It's sublime.
