Got a good deal on a room at the Delta Chelsea on Hotwire...they gave me a lot of information about the express bus from Pearson Airport to their location, and it was great.
The lobby was always packed with people but the front desk staff were very friendly while remaining very professional. Color coded key cards lead to color coded elevators that take you to your room.
The room was fairly large in size and very, very clean. Large windows with a balcony that looked right out onto Gerrard and Yonge Streets, awesome views.
The food in the hotel is expensive, but there are tons of nearby restaurants and it's super close to the Eaton Centre Mall and the TTC stations.
