Hi Mers
Would second the recommendation from Majik about the Novotel Ottawa. I have stayed there a couple of times and found it excellent. Rooms are spacious, very comfortable and the location is perfect. When you are booking you will see the option of the Novation rooms, a bit extra but worth considering ! If you have time to shop just head right across the street to the Rideau Centre, great shopping and lots of places to eat. Enjoy ....
