Luis' apartment was great for our trip to Porto. The location cannot be beat - steps away from the metro and a ton of good food and shopping. The apartment itself was beautifully decorated, with great views of the city and very clean. The beds were comfy and the bathroom was spa ready. Check-in was flexible and very easy.
There was a bit of noise from construction on the market and street noise late at night, but it's a popular area, so it's to be expected - nothing some headphones or a sound machine app can't fix.
