Toronto has a dearth of good hotels. Many of the properties in Toronto are very down at heel. Even the Four Seasons has seen better days.
That being said, I like the Hilton. It is much better than the Sheraton accross the road.
The view from the lounge is North, up University, accross from Osgoode Hall.
Unless I have a good reason to stay at a specific location, I usually pick the Hilton when I am in Toronto.
