The best place that we had stayed in Portugal. Everything is so perfect. It located at a quiet area which is fine for us. If you want to cross the river, walking to the bridge would takes around 25-30 min. But the view along the river is amazing and have a nice walking path. (if you carry heavy luggages, better to call a Uber. it's very cheap)
The only matter is we couldn't find a grocery store in the surrounding.
Other than that, Luis is very nice and helpful.
