Someone I know just carried one from their room to the kitchen; I don't believe that you're strictly allowed to use one in your room; but I doubt you'd get told off.
When my power went in my room the first thing they questioned me on was a coffee maker (didn't have one but it was what they asked about) so they seem quite vigilant about coffee machines. Just have one in the kitchen. Walking down a corridor is hardly difficult or time consuming. Life will be a more sociable experience if you leave your room to get drinks!
