This apartment is in a great location, right in the middle of the city and within walking distance of all the major attractions. There is a great little cafe at the end of the road on the corner called Sabor Da Fazenda (turn left when you come out of the apartment block) which does amazing toast!! A fab little place for breakfast or just to pick up a few cakes and drinks to take back to the apartment.
Eating out in Porto is really cheap and there are lots of local restaurants to choose from. We walked a few minutes and ate near Igreja Do Carmo at Cafe Piolho and O Calhambeque.
We did a 2 hour city tour with Tuktour and it was great. Really gives you an overview of the major attractions and we then went back and visited the ones we wanted to at our leisure. The tour guide was really knowledgeable and took us down some streets that we would never have seen by bus or cab.
