João's apartment is in a great location in Ribeira, a short walk down to the Douro and near great restaurants and bars. João recommended a great little café for breakfast a few seconds' walk down the road. It's a comfortable apartment for four people, with two bathrooms. João was there to welcome us, and as we had to leave very early in the morning when we checked out he kindly ordered a taxi for us. I recommend his apartment as an excellent choice when visiting Porto!
