I stayed at the Hotel Omni over Labor Day weekend. I was there for a wedding and stayed in one of the regular 1-king bed style rooms. Overall, when we arrived, the whole check-in process was great, from the valet to the bellman coming up with our bags. Everything was handled professionally. I requested foam pillows and a bunch were delivered.
The room itself is nice, not gigantic but just big enough. The furniture is modern, the lighting is good and most importantly, the heating/cooling system worked perfectly. The room was clean and had a nice sized flat screen tv, mini fridge and a great view.
I enjoyed our stay at this hotel and would recommend it for anyone visiting Montreal.
