Staying at Old Stone Flats was a wonderful experience. Located right in the historic Ribeira district, the flat was within walking distance of tons of great restaurants, shops, and other landmarks. Our host, Gabriela, provided us with a guidebook full of things to do, and this provided the basis for our whole 5 day stay! She took extra time to explain all of the destinations to us, and was consummately responsive and service oriented. The flat itself was immaculate and comfortable, with great decor and appliances. If you're visiting Porto, you'd be crazy not to stay here!
