Another vote here for the Residence Inn Downtown. It's awesome.
Clean, bright, SPACIOUS rooms, lovely furniture, great hot and cold breakfast buffet, indoor pool, hot tub, business centre, fitness room, and even a complimentary evening social/manager's reception on certain nights of the week...usually Mondays, Tuesdays and Wednesdays I think (enough food that you can easily have dinner at the hotel that evening). Staff are very, very friendly. Some rooms have a view of the CN Tower. Full kitchens in every room (full fridge, stove, dishwasher and microwave). You can get a studio suite (which is like one very large room), or there are also one and two bedroom suites (if you want to be able to have a totally separate sleeping area with a door).
Location is fabulous. Walk to the CN Tower, the Rogers Centre, The Hockey Hall of Fame, Union Station, The Air Canada Centre, Roy Thomson Hall, and more. We even walked to the Eaton Centre (and that was in January, when it was FREEZING...so a walk there in the summer would be a piece of cake). The hotel offers many packages that include tickets to certain attractions plus valet parking...worth checking into.
The Delta Chelsea has some sections that have not yet been renovated.....my brother in law stays there regularly with his family, and would not book anything less than business class. Apparently they have received some rooms in the past that are questionable, andthey needed to upgrade on check-in in order to guarantee the better accomodations that you'd normally expect from a Delta property.
The Residence Inn Downtown is the top rated hotel in Toronto according to TripAdvisor. We had an amazing stay there earlier this year, and wouldn't hesitate to recommend it. You can also get 50% off a second night's stay by purchasing Lays Chips......check out
www.chiptrips.ca for the details. You need 50 points in order to get the 2nd night discount, which is equivalent to 5 large bags of chips (or 2.5 large bags if you get the ones specially marked with double points). Would save you about $100 Cdn. And you would have some comfort food to boot
