This is where you should stay when you are in Porto. It's slap bang in the middle of the city close to Sao-bento station. There are many windows in the apartment that allow you to enjoy morning sunlight and to see beautiful scenery of the church.
Jose is very communicative and responsive. I was worried before as some reviewers mentioned about noise.
Of course there are some noises and kind of vibration you can feel when cars pass by but if you are a tourist, the morning music you can hear the outside windows (magical street musicians) can compensate more than that.
