I always packed a bag with things needed to set up room like bluetack, command strips, tape, scissors, bin bags etc -easy to find the things to get set up. Posters, pics from home nice.
Take the bedding in first and make bed so you can then pile stuff on it to get organised.
Take away as much rubbish/packing as you can. Usually there will be a whats app or Facebook chat for your DS accommodation and then you can see what others are bringing and coordinate things like toasters and kettles.
What is the loo situation? Storage vital so a thing to hook over shower head for shampoo etc.
Don't bring too many pots and kitchen things as again space at a premium. 2 plates, cutlery, a pot, a wok and something to cook in the oven with.
Hanging storage shelf things useful in wardrobe as usually need drawer space more than hanging. Bring hangers.
Laundry basket (or ikea bag for him to take to do his laundry). Usually you have to put money on a card to use laundry facilities so make sure he has money/card to set everything up.
Take some basic food and alcohol to help break the ice.
Not sure what will happen with freshers this year-but a random thing someone suggested to me was fancy dress- always good to have as some night out will be dressing up.
