We stayed in this apartment for couple of weeks. The apartment and services were exactly like they were shown on Airbnb. We could reach out to Luis easily, he was accessible and polite. Our arrival was late at night and Luis was kind to have some groceries ready for us. The view to the river is beautiful.
From location perspective, it is quite functional. The nearest metro stations are walkable (in 1km ball park) but the hilly nature of area means that is bit of an effort. We were using mostly Uber so it was not a concern. Lots of restaurants towards Rossio area.
The room is on 3rd floor, which offers great views to river. Though going up and down the stairs (with luggage and shopping bags) can be an effort. It was ok for us.
One clear downside was the sound insulation. The doors to staircase offer very little sound insulation which can be a problem for people with light sleep. The trash point is right next to building but the collection happens early in the morning and it is quite noisy.
All in all, we had five star experience with our hosts. It was bit of bad luck that for few days there were noisy neighbors who stayed up late with loud discussions
