Truly right on the river, but at the extreme western end of the Cais da Ribeira, so noise was never a factor. If you want to stay on the Ribeira, this is THE perfect apartment. Great starting point to explore the many site Porto has to offer. A beautiful Fado restaurant was literally feet from our door. We got to sit looking out our second-story balcony enjoying a nighttime view of Gaia., truly beautiful. This apartment made our visit to Porto more than we could have expected.
