We just spent a week's vacation in Montreal and were really glad we chose the Sandman. It's right across the street from the Longueuil Metro station, putting you only 2 stops away from the center of town. If you stay out after the Metro shuts down, the hotel is right over the river from Montreal, so the cab ride prices were reasonable.
The hotel staff were very friendly, helpful and fluent in English. The room was clean and comfortable, but the beds may be a bit hard for some. When the bathroom light went out, maintenance was there within 15 min to fix it.
The indoor pool was clean but shallow. There is a small fitness area with weight machines, 2 treadmills and 1 stationary bike.
Overall, we were very pleased and will stay there again.

Excellent Hotel. Everything we wanted. Very clean, tidy, nice Bar, Restaurant area (had a nice breakfast buffet), good indoor Swimming Pool, Carpark (free) and well situated for the Tube to Montreal's city centre. We booked our room on the Internet, a few weeks earlier, with no problems. We flew in from England (UK) to Boston and drove over the USA/Canada border to Montreal. As we drove into Longueuil we had problems finding this Hotel. Perhaps we were getting tired after such a long journey or the map from The Sandman's Web Page was lacking detail, a bit of both I suspect, as we got lost a number of times in the surrounding Hotel's area. So if you're a lousy driver like us, get plenty of Maps of the area printed off first. This is just a minor moan/detail and hope it does not detract from the splendid Hotel. On arrival we were greeted by very friendly and helpful Reception Staff. The one Lady even helped me make an international phone call home to England using their public phones in the reception area. I failed miserably with all the Codes and Language barrier, but she took the time to sort out this problem and my connection was made. I've stayed at other Hotels and asked for similar help and they will not get involved....so, well done that lady! The Sandman Hotel was a good choice and would use (and recommend) this Hotel again on our next visit to Montreal.

Excellent location directly next door to Metro station. A quick 10-minute train ride to downtown. Free parking for hotel guests and accessibility to transit across the street made for easy travels all over Montreal downtown.

Apart from the location, this hotel has AMAZING value! It might not be downtown, but it is quick and easy and almost half the price! We paid $100 CAD a night and similar 3.5 star hotels downtown were charging upwards of $160.

Indoor pool and hot tub were great and breakfast buffet (although very busy) offers a great selection and price. Front desk staff helpful and courteous. Will return anytime!!

We had a one-night stay, en-route to the States. The Staff at Reception are most helpful & friendly. The hotel is clean. Rooms & bathrooms adequate. Beds comfortable. Nice & quiet on the Sunday night that we stayed. The pool & sauna we had to ourselves on Monday morning. Location is excellent proximity to major highways. We would definitely consider Sandman Longueuil for a stop-over again. Excellent value for the money...we had booked on-line with Sandman's own web-page for $85 prepaid a couple of weeks in advance. Parking was free.
