Good site (but for US apartments):

Read your lease well; you may have to supply rugs to cover a certain percent of the floor space, for example, if you live above other people. Check to make sure you know who has keys to your apartment and/or request them to change the locks before you move in and make sure you know who "they" are and how they get access to your apartment. You don't want an apartment where 42 people you don't know are running around with skeleton keys or something and can lend them to their friends :-)

If you have a car, check parking, how easy/hard that is and whether it's worth renting a parking space and what it's like coming home later at night, in the rain and snow, and all that.

Start exploring your new neighborhood now; maybe start a notebook with hand drawn maps and locations of library, grocery stores (find 2-3), cleaner, drug store, start collecting take-away/carry out/delivery food brochures (just go in and get one) and make sure they or your friends show you how to run your air conditioning/heater and all that and inspect the refrigerator for controls and where they're set (you can make your own refrigerator colder/warmer!) and whether the freezer is frost free and the oven self-cleaning and how all that works. There's lots of "automatic" appliances, machinery and mechanical stuff in an apartment that we don't think about but is good to think about, especially if you've never had to think about it :-)

Do you have enough lamps? Lighting is very nice to have and often overlooked. Check location of outlets; you may not want the bed in the bed place, that might be better for an "office" or couch, etc. Look at where the windows are and which direction they face and whether sun will come in and blind you and think about what time of curtains/blinds, etc. you might want (or not want; I lived on the 6th floor so not a whole lot of people could look in besides the birds and squirrels that eventually got that high in 13 years as the tree grew outside my window :-)

My stepmother and I got into a fight setting up my apartment because the building was on a "hill" and she didn't like where I wanted to put the bed because then my head would have gone downhill! I liked my furniture on the rug and she insisted I put it part on and part off or the rug would look like an island. Mostly think about what you like!

Did you get an iron and ironing board (do you need them?). Think of kitchen "machines" you might want, tea kettle, coffee pot, crock pot, blender, hand mixer. Did you get a broom and/or vacuum? TV trays are nice; they're cheap "tables" to have next to a favorite chair and/or can be set up so friends can eat easily while sitting on the couch/end of the bed :-) I had a wall clock or two, one for the kitchen and one for the "main" room. Bookcases/shelving? I have nice stacking bins too for miscellaneous stuff/storage. Clothes basket/bag for laundry to laundry machine; pretty basket/bowl for collecting loonies to do your laundry in machines?
