Looking for accommodation tips at Ottawa, Canada

Hi all!

I'm right now looking for accommodations in Ottawa, Canada. I'm going to do a presentation about Npgsql at PGCon2008 and as I never went to Ottawa I don't know of any good place to stay. If you have any tips about cheap hotels, hostels or anything , please, let me know.

Thanks in advance.

Update: I'd really really thank you all of those who gave me tips about places in Ottawa. I already did my reservation and hope to see you there at PGCon2008!!
