You get what you pay for
What you see is what you get, at the price you would expect.
The lobby smells a little stale, like the carpet hasn't been cleaned in a while. The staff is friendly and helpful. The breakfast is unexciting, but adequate, with eggs, some fruit, bread, waffles, cereal and youghurt. The "fitness center" is a very small room with a cyclical cross trainer, running track, bicycle and a few weights. If that is what you need, fine. 
The room was fresher than the lobby. Everything that should be there, was: internet, TV, heating, safe, coffee maker, etc.
The location is close to the Seattle Center and the monorail. Walking is about 25 minutes to downtown.
If go back to Seattle, with the same budget I wouldn’t mind staying at the Travelodge again.
