The location of the apartment is absolutely fantastic as it overlooks the Duoro. The views are calm and gorgeous!! While there is a popular restaurant below and voices can be heard at times, it is not a big deal. A river taxi can ferry you across to Gaia for wine and Port tastings, but to walk across the is quite easy as well.
The apartment is smaller than what the pics might suggest, but comes with excellent heating, Wi-Fi, a fully fitted kitchen with everything that one needs. There's no washing machine, but a laundrette about 3 mins away can sort that out quickly.
Do go through the black guest book on the chest of drawers as it has wonderful suggestions from other travellers on their experiences in Porto including where to eat, wines to try and a lot more :) The tourist info is in the second drawer.
Finding the street address on Uber was impossible for me. So, I'd suggest you use "Bachalau" (the restaurant that's under the apartment) as your destination. You will be dropped off in front of McDonalds but don't stress :) just take the alley to the left of McDonalds, then the first right and you are at Travessa do Outerinho in under a minute.
Book without hesitation for a wonderfully remarkable Porto experience!
