There are about 5 Hilton-branded hotels at this airport but we choose this one due to the points + money cost (15K points plus CAD 75) and the indoor swimming pool advertised.

We check-in early around 11am and are given a slightly upgraded room on the 16th floor. A signature cookie is given to us which we take to our room to eat with a coffee. The room is well appointed, has an amazingly comfortable king bed, and all the expected amenities are there.

During our short stay we use the gym, swimming pool and spa, and enjoy our Diamond complimentary breakfast in the morning.
We check out very early in the morning and leave our bags until midnight before taking the complimentary shuttle back to the airport.
There are many reviews on the different Hilton branded hotels in the vicinity. Which is best is hard to tell, but we were happy with this one.
