I really liked the Frontenac, great location and very nice room. The caveat is that as a Platinum with Fairmont I never end up in the small rooms so this was not the lowest class of room, indeed I believe it was a couple steps up (hmmm..although last summer I was only Premier but still got an upgrade).
The fitness centre and pool are newly renovated and very enjoyable. There is definitely an ambiance in the hotel and the staff provided exemplary service. Certainly would love to stay there again
