I had a very nice stay at Staybridge Suites, this hotel is clean, soundproof, very comfortable and nice amenities like stove, full size fridge, dishwashing machine and dishes.
They even offer free drinks and dinner on Monday, Tuesday and I think Wednesday to promote exchage between guests.
The only small downside for me, is that they do not offer a full room cleaning service when you are staying several days, I was there for three nights, they only make the bed and replace towels (which I think would't be necessary if you do not require it), but where I have a problem with the cleaning is that at the entrance of the room, you have a hard floor, during my stay there was snow outside and even if I had to walk quite a bit to get to my room, my shoes were still wet and it made quite a mess on the floor, mopping takes a few seconds and could make a world of difference.
