Please respond to the email below. Use a friendly and helpful tone. Tell them that I'll send that to housing to consider. Let them know that they have been getting a lot of requests in the last week and might be slow getting back to them. Make sure the main paragraph is less than 50 words total.

Hello!
I was wondering if I could pay for a single room next year and still be on the same floor? If that is at all possible, please let me know! 
I'm sorry for the trouble.
Hi [name],

Thanks for your email. It's no trouble at all. I'll submit that request to the housing office for you. Please note that they have received a lot of requests in the last few days and it may take them a few days to get back to you.

Let me know if you have any other questions or concerns.

Kind regards,
