For a Sheraton, pretty nice.
Given upgrade to junior suite, which was fine. Rooms are pretty typical of Sheraton/Westin quality.
Platinum lounge was great - good appetizers, very good view of the city. Similar to the Toronto Sheraton lounge.
Pool/gym/sauna were all of unexpectedly high quality. They were all larger than I'd come to expect for business hotels. It wouldn't replace your gym membership quality experience, but pretty good.
Location was above average - I felt like I was a short cab ride from every location I wanted to check out. Close to a metro station, however.
Solid hotel - better than your average Sheraton.
