Like most three star hotels, the Radisson is okay. I booked on Hotwire for a bargain-basement ~$75/night.
Of course, booking with a super discount rate meant that we got rooms facing the street instead of the lake -- I'm sure the lake-facing rooms are way cooler and have sweet stuff like telescopes, but the street-facing rooms are pretty basic. No telescopes, just two double beds and an alarm clock from the early 90s. Clean, decently comfy beds, a few hangups with the shower, free wifi.
Mediocre rooms aside, the location is pretty good. It's easy to get anywhere downtown, and easy to hop on the Gardiner Expressway if you're heading to points outside the city.
I'd stay here again, but probably not at the full asking price.
