A little confusing to figure out how to get to the main floor and reception area at first but once you got it figured out it's fantastic.
The Hilton is located downtown right near all the action of St. Catherine and Peel Street. The hotel itself is located on the corner of Rue Mansfield and Rue de La Gauchetiere. McGill University is a straight shot up Mansfield so if you're looking to visit some friends at McGill you're not too far off. Also Crescent Street is not too far from the hotel. That is where you will find the Hard Rock Cafe, Thursday's, Sir Winston Churchill's, Ben & Jerry's, Newtowne, Paris Crepe, etc. Just travel a few blocks west on St Cathrerine and take a right on Crescent.
The hotel atmosphere is quiet and nice. It's in an old building that could appear to some as dingy for a Hilton, but it's actually quite nice. The hotel bar staff and reception desk clerks were very helpful and friendly. Warning for the bar: a tall cheap beer (Molson Dry) ran me $10/each. It shouldn't really cost much more than $7 elsewhere.
The hotel has free internet but not wi-fi. In your room there is a LAN wire that you can conntect to your laptop. You can purchase higher internet speeds for a certain price per MB.
The bed was the most comfortable thing I have ever slept on and the rooms are spacious. I will definitely be back.
