We stayed a week in Porto and had a wonderful time in Fernando's apartment. The location is just perfect. It is super central, close to the main tourist attractions, shops and supermarket. There are several traditional restaurants in the road and I would recommend to go to the All In Porto, the food and wine are amazing there. The nightlife clubs are just 5 minutes walking distance and we got lots of transport options around, although we often took Uber which is super cheap.
The apartment is very clean and about the right size for a couple. The neighbours were quite during the week so we didn't have problems with that and the road is not noisy at all.
Highly recommended.
