Great sized apartment in the middle of tourist zone. Mario waited for our flight to arrive (which was late) and we checked in without a problem. Lots of natural light too, however, not as white, bright and clean as the photographs depict. It's an old apartment which is fine, however, the apartment was uncomfortably unkempt (stains on walls, dust, moldy bathroom, stained rugs and pillows). Could use a good deep clean, fresh coat of paint, and perhaps some new furniture. For the value that it was listed for it was not worth it. Other than that, it's a good location if you want to be in the center of Porto's major attractions. It has a lot of potential and I'm sure Mario will have fixed it up by the time I finish this review.
