You're going to want to find out a few things. I ofter try to look at what it will look like when you go to move out; ie, what you're obligated to pay and cover and so forth. Like if there's damage to the apartment or something of that nature. I also look at the location. Find out what services are truly going to be covered in your apartment, with furnishings and repairs and things. Hidden costs can be tricky. Ask about everything and don't accept anything but truly straight answers.
