There's no harm in asking. If you really dislike where you are now and it doesn't seem like some things will change (meals times, shared bathroom etc), then as it's still fairly early on in term, hopefully you could be moved to an accommodation you prefer. They might not be able to give you exactly what you want (or they could be fully booked so might not be able to change your accommodation) but it's always worth asking.
I hope this helps,
