Looking for rent in Kettering from Feb/April

I am looking for a shared apartment or even a sofa to crash for me nearby to the area of railway station or Kettering general hospital.
I actually have my own place in Leicester but I work in Kettering hospital and do train commutes. Whenever i am on long shifts or nights or if trains are cancelled, those days I would like to have a back up place in Kettering to stay or crash for the night. I don’t mind paying as a regular tenant.
Or we can also come up with some arrangement where I pay per day/night that I stay over as it will happen on only need basis.
I am a very quiet, introvert and unproblematic person and mind my own business.
