We traveled with 8 friends over Memorial day weekend. All 4 rooms we booked were different layouts and spacious and clean. The location of the property cannot be beat - you can walk everywhere in any direction to go to Old Montreal, residential neigborhoods, parks and dining and bars. Everyone at the hotel was friendly and the exchange rate from USD at the front desk was the best around!
We took the metro up to the Olympic Park & Botanical Garden and went to the underground shopping mall that runs for miles. We visited countless bars and taverns and all were unique and fun and we walked around for hours to see different neighborhoods and sites. Don't miss the Notre Dame Basilica - it is really unbeilveable!

We booked the prez suite here because we couldn't get in at the W on the big UFC fight weekend. They gave us some lame excuse about how the person in their prez suite had extended their stay...and recommended the OMNI...whatever.
The only thing that was nice about the room (s) was a big 2 story sitting room on the top floors which adjoined to our (normal) bedroom and it was close to shopping.
But...all the carpets needed to be replaced, the furniture was cracked, dented, scratched, bathrooms were ancient, poor lighting throughout, reeked of smoke from the last "party" that took place in there ...I could just go on and on.
If you are looking for a 5 star experience, this hotel is NOT it.

We stayed in this hotel over the Memorial Day weekend. Great location on rue Sherbrooke West and within easy walking distance to the Peel St. Metro, McGill University, Bell Centre, Museum of Fine Arts as well as all the downtown attractions, restaurants and shopping including Old Montreal.

Nice perks in the room; including an umbrella in the closet which we made of use of because it rained during our second day there. Avoid the in-room bar and snacks which are way overpriced.

Money changing at the hotel front desk ($US to $CAD only) was at the best rate we encountered in town. Money changers, located in small shops all over downtown, offered 1% less. The Montreal Casino offered the poorest exchange rate we encountered.

Staff were courteous but not overly-friendly; very helpful and knowledgable.

Car park was in a nearby underground garage at $16.75CAD per day. Valet parking is also available at about $26.75 per day, unlimited in/out. Given the proximity of the hotel to the downtown and Montreal's good public transit, save yourself some money if you drive into the city and self-park.

I am late in writing my review of this hotel which I have stayed at in April 2007 for a family reunion and again in January 2008 for a girlfriends weekend through Travelzoo at a great promotional price of $89 and $99 a night.
I would recommend the Omni for it's great location close to a large choice of restaurants and shopping area.
Overall our stay was pleasant,the room & bathroom clean and spacious.The beds were comfortable,linens were good ,rooms soundproof.Would recommend to stay on the 20th floor or higher for the grand view of the city.One complaint for the bedding was that the pillows were too small /flat and not enough extra pillows in the room or closet.The furniture was a little tired looking.
The small restaurant on the main floor entrance offered a large buffet breakfast for a reasonable price.
Did not take advantage of the gym but did visit it and looked well equipped,was very interested in the morning yoga class offered but slept in and missed it!A heated outdoor pool was used by my daughter in chilly April.
The staff at the reception were welcoming,we were allowed to safely leave our luggage at checkout time so we could do some last minute visiting,the concierge was helpful in recommending a good french restauran(actually right next door 'Garçon !' is an excellent restaurant with a very good menu, professional staff and wide selection of wines.
I would recommend this hotel to my friends visiting the great city of Montreal.
