I am a mid-thirties PhD student living in a great 2 bedroom second story walk-up apartment just south-west of downtown. It includes a washer and dryer, two balconies, internet, cable, home phone, and the use of a bike. There's a large grocery store 3 blocks away and an indoor/outdoor Market 10 minutes away on foot. Several parks and the lovely Lachine Canal are within walking distance, and there is an ever expanding variety of restaurants popping up in the neighbourhood.
Though it's a pretty quiet part of town, there's a metro station literally 2 minutes away that will get you pretty much wherever you'd like to go (Like the Jazz Fest, maybe? June 28th-July7th).
I have two cats who would require some of your attention (don't worry, they'll let you know the when and the where). They're both quite friendly and sociable. You're responsibilities would be litter box cleaning, feeding, watering, and, of course, playing.
