The rent is located near a beautiful old church and near to nearly every attraction on this side of the Duoro. The rent itself is cosy, but nicely used and ideal if you plan on visiting Porto for an extendet weekend. One big issue is just, that it is very loud (the windows do not close perfectly and the rent is next to a metro station and highly frequented road) und very bright in the morning. So that might be problematic if you have a light sleep.
Best regards!
