We had a great stay at Helena's she was very nice at our arrival, the studio wasn't like in the picture, the decoration was simpler and less refined but the configuration was the same, we realized later Helena has many apartment on the same building. However we where happy to have a balcony with a view. The area is great, near to everything and just under a place called Guedez with the best pork and cheese sandwiches ever! Everything went great the only bad point for me will be the pillows a little bit stiff. In overall good place for you vacations in Porto I would definitely recommend Helena's place.
