This is a great place for the price an overnight in Lisbon. The metro from the airport takes you virtually to the front door. (about 5 minute walk through beautiful marble-paved pedestrian walk-way). You are then smack in the middle of a very desirable, fashionable area full of out-door restaurants and nice shops. Obviously, there's going to be some noise from the street... but it's purely pedestrian. I liked that I could experience a bit of Lisbon on a quick overnight between flights.
