Mariana’s apartment was just as described. It’s in a very convenient neighborhood, only a short walk from Sao Bento train station and other attractions. As it is on a quiet street it is not too noisy. It was well equipped and has everything you need for a short stay in Porto. It is on the 3rd floor so carrying heavy bags is a bit of a challenge. Mariana herself was quick to respond to any questions I had. We would recommend staying at Mariana’s apartment.
