Francisco and Maria's airbnb was right in the middle of everything we wanted to do in Porto and had a beautiful backyard with amazing views. It was decorated well and easy to check in and out. The only problem we had (no fault of the host) was that there is construction going on in the building next door, which starts very early in the morning and continues until around 7PM. The noise comes right through the walls and unless you're already awake and out the door by 8AM, you won't need an alarm clock.
