This was a great base for exploring Lisbon. It's close by to the trams and buses that go through Alfama and of course it's easy to walk to the restaurants and sights in the area.
It's located in a pedestrian only area with steps in all directions, so take that into account if that's a problem for you.
The flat is on the second floor on a pedestrian street and doesn't have any restaurants right next to it so it's mostly quiet.
