Each property manager does things a bit different. Make sure to ask what supplies they bring & what you'll need to bring. GET IT IN WRITING!
Here is a list of things you may need:
wash cloths, wash towels, shampoo & conditioner, wash soap, toothpaste, shaver & shave cream, lotion, sheets, extra blankets, pillows, food, games, cable to hook into internet, paper towels, hand soap, toilet paper, DVD's, Etc.
Some will provide a "starter" batch of things like toilet paper, hand soap & paper towels, but always ask.
