Spare bedroom needed for GAP year student

Saving up to go to uni abroad and have recently landed a full time job position in an office in Gloucester so need some where cheap to stay within easy walking distance/ bus commute from work and so that I can save as much as possible for when I go to university abroad next year to study cyber security engineering since I won’t be able to take out a loan abroad. I am a runner and in my free time I teach myself new technical skills. I don’t smoke, I don’t drink alcohol and I don’t go out clubbing/ parties.
