Arlene's place is adorable. I was slated to stay there for a month and ended up finding an apartment within my first week, and Arlene was extremely understanding and accommodating. The apartment is adorned with personal touches like a welcome basket of tea and snacks, and all the amenities you might need for your stay (dishes, towels, stovetop, DVD player, the works). The height of the place never bothered me at all, but I'm only 5'3", so I can't account for how it might be for taller folk. Everything was set up and ready to go when I got there, and it made settling into Toronto much easier. As Arlene says in her description, you can hear much of what goes on above you, but they are extremely careful with the noise, so it was never an issue for me. Situated right beside a train station, it's extremely convenient to get around (when the train is working). And if you prefer walking, there's everything you'd need right around the corner (Tim Hortons, Starbucks, Shoppers, Loblaws, even a dollar store). Definitely worth a stay if you're passing through the area.
Also, the bed is the most comfortable thing I think I've ever slept on.
