Joao (John to make it easy for me) is a very personable young man who loves his city and will taylor his suggestion about what to see or do to your ..... particular demographics.
A very nice apartment, well provisioned, and centrally located. 10 to 15 minutes walk either direction virtually covers the downtown Porto.
Ask Joao and he will respond with excellent help.
Full marks!
