I stayed at the hotel on Memorial Day weekend for two nights. It's a standard Marriott hotel with the standard setup. We got a great deal by using the Sweetheart Deal (check their website). The best parts of the hotel:

1. good location - centrally located so you can walk everywhere, or take the nearby metro if you need to.

2. good value - check the website, we got the 2nd night at 50% off.

The worst parts:

1. There is construction going on on the buildings on both sides of the hotel. Wasn't really a big problem though.

2. Tiny bathrooms.

The Montreal Marriot Courtyard has a excellent location in downtown Montreal. It is an older property and unlike the vast spaces that are expected, the hotel has a no frills - straight to business - attitude about it. The reception at the left and the miniscule lobby leads to the lift. The rooms are large and well lit.
Wifi all over is a great asset for the business traveller. The beds are clean and comfortable. The management was prompt in sending up a fridge when requested. The coffee machine did not heat up the water.
The price was a bit on the higher side. At $135 per night it was certainly high. Would have been fair if it included breakfast.
Overall experience was average, but given the location, it was worth the price.
Do look up the Tourisme Montreal site, they have additional discounts and interesting gifts.

The property is in a great location on Sherbrooke and an easy walk downhill to the Bay and downtown shops and nightlife. The concern I have with the property is the iffy service. The check in process with the front desk is pretty painful. They don't really understand English very well, which makes for a communication barrier from the very beginning. The front desk agent I had (female) tried to make the check-in process so quick it seemed like a fast food counter. She really did not listen to my questions or my needs. When I later asked for directions to the airport, I got the same vibe. The feeling you get is that they do not wish to speak to their customers.

If the property could fix its front desk accumen, it would be a much better property.

1) When I checked in the clerk tired to give me a higher room rate. I had different rates for the 4 days but the clerk adamantly said my rate was the higher rate for all 4 days. Even on her check in card the rate written correctly displaying what I was saying. Even after explaining to her she did not agree to the rate and went in another room and spoke to somebody and came with the same higher rate for all 4 days and now she had scratched the lower rate from her card. Thankfully I remembered that I had printed my hotel receipt at home and packed it. I had to fish that receipt out of my luggage. Finally only after showing that I got the rate that I was entitled to on the first place.
2)There is only Valet Parking at this hotel. On 8th May 2008 I went down to get breakfast (around 7:45 am), and saw my car parked in the lobby. I was concerned since I had not called my car; the Valet brings the car to the front entrance at the request of the client. When I spoke to the concierge they brushed me saying it must be a mistake. I am skeptical though and wondering whether my car was being used illegally without my permission.
