Not just the best value around
If square footage matters to you, then the Chancellor might not be your first choice. But if you are looking for a clean, comfortable room close to many attractions and transportation at an excellent rate then there is only one choice. From check-in to check-out the folks at the Chancellor were great. The room is modest in size, but really all you do is sleep, and queen beds are pretty much the same size no matter where you go. 
One simple thing they have are great windows. With them closed they block almost all street noise, the only noise that got through was heavy street grinding that was happening down the block. We might not have even noticed it, but we enjoyed leaving the window open at night (for safety it only opens a little) and listening to the sounds of San Francisco as we went to be each night.
This is a great place to stay if you want a good value close to everything, but not if you are after a cookie cutter room (for twice the price) of the big chains.
