If you are looking for a great location, this is it. Walking distance to all sights, we even walked back from Foz, a lovely 60 min stroll by the river. On the street, there are also two markets if you need food or water. The street is quite lively but the windows are tight and when closed, the apartment is quiet.
The apartment is great for two people, warm and clean. They met us at midnight for check in. No food in the kitchen, though, don't expect it :) all in all a great place in a superb location!
