This clean, modern apartment is located very centrally in the old section of Porto, directly behind the Clerigos Tower-- whose bells, by the way are exceedingly quiet. We were able to walk easily to many interesting parts of the city and to two metro stations, the Sao Bento train station, and the #22 tram, an antique streetcar. Good cafes--especially the Clerigos Bar on Rua da Caldeireiros--are everywhere. Mario was an excellent host who handed us a map and showed us how to get around the city.
