Great location close to all the main sights of Porto. Beware there are quite a few steps up to the apartment so might not be ideal for anyone with mobility problems and you have to be prepared to carry your luggage. They do appear to be installing an escalator though so hopefully things will be easier in the future.
The apartment is nicely furnished, lovely and light and has great views of the city and river. It's great to have a balcony, we enjoyed sitting outside with a glass of wine. We really enjoyed our stay.
