Professional seeking a room to rent

I am currently looking for a room to rent due to work commitments.
I work away part of the week also around the UK and often stay away 2-4 days a week and working from home 1-2 days a week.

I am a keen gym goer and sociable and like to keep myself to myself also sometimes.

Being ex army I am a clean freak so you don’t have to worry about any mess.

Looking for Northamptonshire, Cambridgeshire and Bedfordshire areas only.

Thanks in advance.

£400 - £600 max budget.
