The hotel is located conveniently at Highway 7 and Interstate 404, which leads directly to other central Interstates in the area. BUT: it is at least a 30 min drive to downtown, depending on traffic up to an hour. That is the most problematic aspect about this hotel. Otherwise it is great, especially because you can get rates that are less than half of what you pay downtown. The rooms are spacious, very well and comfortably equipped (flatscreen, complimentary coffee, WiFi, nice work desk, a couch) have a great bathroom and in all feel very cozy. The hotel adheres to Hilton standards, even though it is the lower price range of the group. The staff is very friendly. Lots of on-site parking.
So, if you are looking for a lower budget and don't mind the drive, here are some really good options.

I had a one night stay for business at the HGI Toronto/Markham. Hotel was located in a nice area with many restaurant options to appeal to various tastes (try Jack Astor's). All the right amenities parred with fine service. Breakfast was a bit odd in the morning, but I think it was just a strange day. I contracted the manager via email, and I felt that she was truly interested in understanding my concerns.

Thank you for responding in a timely fashion to a direct email!

Have had the opportunity to stay at this property several times now. ideally suited for the business traveller. Close to major routes and to local businesses. Has on site bar and restaurent, and is also very close to a number of good restaurents and bars.
On site work out facilities, free parking, and the rooms are typical Hilton quality. Beds are comfortable, good flatscreed TV witha good selection of channels. Had in room safe, iron, board, and decent work station.
Service was very good and I would highly recomend to fellow busines travelers if in the Markham / Richmond Hill area

I recently spent ten days at this hotel and, believe me, they try hard. The staff are friendly, helpful and everyone seems to go out of the their way to make sure you are happy and comfortable. The only drawback is the city of Markham.
The entire time I was there, they were ripping up the road directly under my window. That isn't normally a problem except that the City of Markham feels it disrupts traffic less if they do the work at night! Starting at 10:00 they work through the night with the damned gravel trucks ensuring they make the most noise they possibly can and the compactors doing their very best to make sure you don't sleep!
If you do have reservations, make sure you are assigned a room anywhere but the North side - regardless of the floor you are on.
