Yes the comfort is quite basic: bed, desk, mini-fridge (a nice surprise) and in room sink. But who needs more while in London.
I concur with previous posters as this is an excellent accomodation for the price paid (about 65$USD/CAD or 32£ a night). Staff is very helpfull and the fact that your staying in a student dorm makes you feel like a 20 yo. again.
Remember those carefree times when the whole world was yours to discover. And the Carr-Saunders Hall does just that! Location is very close to Tottenham Court Road with fabulous shops and restaurants. Tube station is 2 corners away, right in front of two late night supermarket. You can easily walk to all the attractions as well or tube it (get an Oyster card folks, its cheaper that way).
Last recommandation I would make would be to get some nice pajamas as the rooms are not ensuite (ie, you have to share a bathroom/showers with people of different gender).
Once again, its all part of the experience!
