Ottawa's Fairmont Chateau Laurier

It’s not every day you get to stay in a downtown castle, but that’s exactly what staying at Fairmont Chateau Laurier was like.  Finished in 1912 it’s a very old hotel but has all the charm and style of a modern boutique hotel.  The location was great for walking around downtown and generally exploring the city.  Being in the capital of Canada meant that there would be Canadian touches to everything, and the Maple Crepes from breakfast were just one example.  I love hotels that are so memorable I will cherish the experience for years to come, do you have any stays that stick out as fond memories in your mind?
