We enjoyed out stay at Paulo's very much.
Paulo was easy to reach. Upon arrival he gave us a bunch of tips including a map and a list with his favorite places in Porto. The accommodation is located near a lot of art shops, which was a plus for me. It's close enough to the centre and there is a bike rental shop almost right around the corner!
The room itself was clean, had everything we needed plus a gorgeous view on the building and little garden across the street.
