Bedding is a must. Perhaps some kitchen bits and pieces which you can wash and keep in your room. The shared kitchen will have a fridge, cooker and microwave but do not have pots, pans, plates, cups etc. If they do then you can be sure they will get used and no one will clean them. The last thing you want to do is have to scrub a frying pan with green mould growing in it and then cook your egg in it. You need to buy your own food if you are in the kind of accommodation which does not have pre-paid meals.
