You might hesitate over the location, but it worked well for me. It is about a 20-minute walk to the center of the city, but it really didn't seem that far. The location is next to the train station and near to the cruise ship terminal, but it is actually very quiet. Just the occasional train or ship horn, but they're just letting you know they're on the move so that you can watch them maneuvering. It's a top floor, 9th floor, apartment, with a great view across the river. There was no noise from any of the other apartments. The hosts were very gracious and accommodating. The greeter/cleaner is quite a character... you'll learn some Portuguese... she's fun... ;)
