Old Stone offered everything necessary for an excellent Porto experience. The location provided easy access the Flores St. as well as a quick walk downhill to the river. There was a small fruit market 2 doors down and plenty of dining options. I recommend Prega, if you can fit it in, but there are many cafe options that also serve excellent food and you get the bonus of street performers. Even though the neighborhood is lively, the windows at the apartment kept the apartment quiet. Ubers and taxis were a little challenging, but probably because I never did figure out the road system! It wasn't expensive even though the route seemed circuitous.
