£20 a night is fine for food. I was placed in central London on that exact amount and was fine on it. I had to live in a hotel for 8 months Monday to Friday.
It's horrible being away from home and I quit when the project was over as I wasn't going to do it again, but I got the job done.
Sharing a room will be horrible though so that is the one thing I would say no to. I always did the job I was asked but would never share a room as living away full time is hard and having your own space in the evenings at least let's you call home, have a beer or watch a film to get over the days work.
