When I visited a friend in Toronto I stayed at a Toronto bed and breakfast and it was one of the best places I ever stayed at. The place is lovely and very homey. It felt like I was just home. I will surely come back to that place when I go back to Toronto soon.
Of course, for those who wants their utmost privacy and would not want to mingle with other guests, there are Toronto Hotels for you to stay at. There are a lot of Hotels in Toronto that one can choose from. Even BedandBreakfast-Toronto.com has some up their sleeves. You might want to visit their site to know more about this.
