This apartment was clean, spacious, and comfortable. We arrived later than expected, and Helena was happy to meet us at 2am to let us in and briefly give us an overview of things to see and do in Porto. Great location, just a few minutes on foot to the center of the city and maybe a 15-20min walk down to the river. The apartment was also very quiet given the level of noise from the street below. We expected the worst, as we arrived when the bars were in full swing, but the noise was never disruptive. We would happily stay here again.
