Staying at Joana and Ana's place was wonderful. They both are good hosts and the appartement is very nice. It's clean, feels like it's new and makes a perfect place to stay while getting to know Porto. The appartement is located in the heart of the old centre, close to everything you want to visit, like the waterfront, the port cellars, the (incredibly beautiful bridge over the Douro) and much more. Last but not least, the breakfast in the family restaurant was nice. It's a good way to start the day.
