We took train to Montreal so we wanted to stay somewhere near the Station. It turns out the hotel is very centrally located with walking distance to old town, central shopping areas and even the Beau Art Museum de Montreal. Hotel was modern, efficient, clean and spacious. Continental breakfast was also sufficient, with several kinds of bread, yogurt, fruits and boiled egg. Overall great value for the money and would highly recommend it to anybody.

I stayed at Hotel Dauphin when attending a conference. The conference centre (Palais des Congres de Montreal) was almost next door so that was great, and the Hotel is essentially on the edge of the old town and downtown so it was an easy walk to pretty much everything I wanted. Plenty of restaurants and places for a drink within 10 minutes walk.
The Hotel itself is reasonably basic, but the rooms are very comfortable, modern, clean and it is quiet. Fine for a business trip. There is even a computer in your room which you can access the internet from for free, but I struggled getting it off the French language setting. There is the usual tea and coffee complimentary but with the bonus of coffee bags being let down by having to use powdered creamer.
Breakfast is self serve in the small dinning room with basic cereals, bread, pastries, yogurt and fruit available. More than enough to fill you up if you like things reasonably simple. The coffee is from a machine as well and passable, just.
If you want to stay in the same area with more luxury etc. the Intercontinental is only 2 minutes away on foot so has all the advantages of the location. It is 5 star so it is naturally going to offer more but I suspect at a greater price ( I did not compare prices myself).
All in all I enjoyed my stay at Hotel Dauphin and I think it is more than adequate for a business trip, but if you are on holiday and looking for a bit more then perhaps you should consider other options. I did feel let down by the breakfast, particularly the coffee. It is a good hotel with good staff, I would give it a 3.5 if I could. Above average but not quite what I would rate as very good. For the review I'm going to round the rating up.

The hotel has a good location in the center of Montreal - it's within short walking distance to China Town (east), to the Festival Place in the modern center (north), and within a longer walking distance to the old town (Place d'Youville, south) and to the Cathedrale Marie Reine du Monde (west). Right in the center, which allows you to walk a lot around the city.
Although there are many parking places on the street, they are all for a limited time, with meters. You can use the hotel parking for 20$ per day, but take into account that the parking is very small and the space there is limited. The parking is located in a small garage on a parallel street.
Staff is very friendly and speak English fluently. Though I should say that the restaurants they recommended us weren't so good (one was even very bad).
The room was clean and good. We stayed at room 101. The bathroom was big. The shower head was hand held. There were too few electrical sockets in the room and they weren't conveniently located.
They have free good wi-fi, and there is also a table computer in each room - its softwares are not updated (to protect it from viruses), but it was nice to use a normal computer during a long trip.
Concerning breakfast we had 2 different experiences - it was missing an omlette, but in our first day, there was plenty of other stuff to eat. There were hard boiled eggs, sweet beans, 2 sorts of cheddar cheese, good bagles, philadelphia cheese, croissants, cereal, jams, honey and good coffee. However on our 2nd breakfast there, we were diappointed to find out that foods which were finished, weren't being replentied. So there were no more bagels and other stuff we liked to eat in the first day.

Everything was perfect. Great location just by MTL Congress Centre and at a walking distance of almost everything!

The matresses are a bit hard but I slept very well. The hotel was very quiet and I enjoyed the free continental breakfest. Well priced hotel and good value.
