Maria's apartment is exactly as described. It is very well located for tourists who want to explore Porto on foot. We were able to walk to all major attractions without much difficulty, although remember that Porto is a very hilly city with lots of ups and downs no matter where you stay! We were late arriving due to traffic problems but with a couple of phone calls we were able to get access to the apartment. The secure indoor parking is a big consideration if you have a car, because you will probably prefer to walk or use cabs rather than try to drive around Porto!
