I like the convenience of renting an apartment. Assuming your landlord(s) does his/her/their job (if he/she/they doesn't/don't then it can really suck) and you rent in a halfway decent place.
I don't want to worry about shoveling snow, cutting the lawn. It's taken care of.
If something breaks it's not coming out of my pocket.
You don't have to worry about ridiculousness electric, heating, and cooling bills.
You own less junk, because you have less room for the junk.
You know exactly how much you have to pay every month and you don't have to worry about things like property taxes, or having to pony up the cash to say fix the sidewalk or repave the road outside your place.
Safety wise there are more people around and it's probably more unlikely (especially if you know your neighbors) that someone will break into your place.
On the downside you're closer to your neighbors, and they can be a pain in the ass. However unlike when you have a house, it's much easier for you (or them) to relocate.
