My wife and I didn't have the chance to meet João Paulo, but the check in process went very well. João Paulo had his friend to meet us when we checked in.
The apartment is located pretty close to where the center is. Restaurants, supermarket, are shopping area are within walking distance. The only thing you should be aware of is that the apartment is located on the 4th floor, and that there is no elevator.
There can be noises from the street at night, especially during the long weekend.
The apartment is very clean, comes with towels, and has a very good view of the city.
