João's apartment is clean and nicely recently renovated. It is ideally located near the Ribeira and central Porto. You can actually see the River Duoro from the window! João was eager to ensure that my stay was comfortable, checking that I had everything that I needed and even asking if there were any ways to improve my stay. It seems that the apartment is still in the final steps of renovation (ie internet not available until July 9th) and will be even better when fully finished. I would recommend you to stay at João's place in the future.
