I stayed here for three nights, over the New Year's weekend...and slept quite well. Osler House is very close to a main road, but in a fairly upscale neighborhood, and even on New Year's Eve, peace and quiet reigned. I had "neighbors" in another room, but I didn't hear them at all.
Gary and Sarah are both friendly and enthusiastic innkeepers, and gave me great advice on where to go and (most important) how to get there. Osler House is very conveniently situated between Niagara Falls and Toronto, and made a great base for exploring the area. Food, a bank, and other necessities are within easy walking distance of the house, as well.
My room was large enough, with a comfy king-size bed and a flat-screen TV. The bathroom floors were heated and the towels were thick and fluffy. Good hot water and water pressure. Sweet snacks were available (coconut lemon squares, for example) downstairs. The house itself has a number of interesting portraits and paintings, antique tables and cabinets, that just scream, "ask me where I came from!"
Breakfast was a lovely three course affair, with fruit, homemade scones (the best ginger scones I have ever eaten in my life), and an egg creation. You have not had eggs benedict until you have tasted it here...seriously. Yum. I was stuffed until dinner.
My stay was enjoyable in every way, and I won't even think of calling another B&B when next I visit the area. Thank you Gary, Sarah, Max (and Waverly and Seth) for your hospitality, and for the gift of three good nights' sleep!
