Why live in a B&B? It is rarely the cheapest option, and self catering can be much more comfortable for that timespan.
Having said that, I started living in cheap full-board lodgings intending to change, and like the people and the place so much I have stayed on. I am paying less than £4000 a year for accomodation, food and even some beer! Varied and cosmopolitan company (Czech, Colombian, Japanese, Polish and Russian at the moment) allows me to get away from aviation in the evening
Cycling to SFT keeps me fit and keeps transport costs down.
Integrated course with accomodation (not all seem to include it, or did I miss something? The difference with an integrated course is you don't need to get a PPL before groundschool, not that accomodation is provided) may help if you have never been away from home, sounds like University halls to me, but if you have lived independently it might be less pleasant, and I can't see it as really necessaryt to have everything provided on a plate.
