We enjoyed staying at the Sandman Suites for 4 nights from Aug 20-23, 2005. We got a great price ($149 Cdn), which is an excellent deal for high season in downtown Vancouver (other hotels I looked at were in the $200-$300 price range for 3 1/2 star to 5 stars). This hotel has a kitchen, including fridge, and washer/dryer combo.
This location is perfect for visiting downtown Vancouver, we were able to walk EVERYWHERE from this location....including Yaletown, Robson Street, Canada Place, ferry to go to Granville Island. For a real treat, walk to Yaletown, rent some bikes and cycle along the seawall to Stanley Park...check out all the cool people and wonderful beaches along the way. You can even catch the ferry to Kits Beach from just a few blocks near the hotel. Even our room with "no view" had a pretty decent view of Davies Street. There are many restaurants and shops open at all hours on Davies. This hotel is located in the heart of Vancouver's gay community. Although all are welcome, if you are easily bothered by this, don't stay here. Better yet, don't go to Vancouver. It is a beautiful city with a very open minded.
The hotel has a nice lobby, and generally friendly staff. The rooms are quite large (living room, bedroom, and kitcken) and have air conditioning. We found the bed VERY hard, so we just pulled out the sofa bed and found that to be comfortable. The room wasn't perfectly clean (ie. we did find the occasional stray hair on our sheets), but then again I've found this is $300 per night hotels.
A comment about parking...when you check in you are told to 'valet park' since it's the same price, but we said "no, thanks - prefer to park ourselves" and they were fine with that and told us where to park.
Overall, I would highly recommend this hotel for a comfortable stay and fun time in Vancouver. Our only suggestion is that you will need more than 4 days to fully appreciate Vancouver!
