Spent three nights at the Benson in Nov. 2012. The hotel is 100 years old, and the lobby oozes with pre-WWII elegance. Lots of wood, chandeliers, marble, and a fireplace. All of the staff are extremely friendly and helpful. Look for Cordell, he can tell you anything you want to know about the hotel, Portland, and the surrounding area. There is also a concierge desk that is very helpful with maps, brochures, advice, etc.
Our room was nice, clean, and had a flat screen TV and minibar. The bathroom was small, but serviceable. Bathrobe and slippers in your room.
The serve an excellent breakfast buffet for $15 each morning in the restaurant/bar at one end of the lobby.
The hotel is within walking distance of many Portland landmarks on the west side of the river, including Powell Books, Saturday Market, and the food trucks.
If you are interested in the excellent Oregon beer scene, take a left out of the Benson's front door and head a block down the street to Bailey's Tap Room. Bailey's has a huge selection of tap and bottled local beers. Also consider the Beervana tour. They will pick you up and drop you off directly at the Benson for a small extra charge.
In summary, the Benson is an excellent hotel, and we will stay there again the next time we are in Portland.
