A shared or single room for 2 days per week

I’m going to be accepted for a PG course in the university of Southampton
I need a room for one or two nights per week mostly in the term time
My budget is up to £190 all inclusive
Don’t mind to share a room with females if there are two single beds available or there are opportunities to have a floor mattress
I don’t cook during my stay but I need a clean bathroom
I guess I don’t use washing machine or communal areas as well except for the kitchen to make a coffee or warm up food
Probably mainly I’ll use the place during October-November and February-May
I have other commitments so being far from my home is not an option and I’ll try to go back home most of the time.
I just want to have the peace of mind that if something happened and I am forced to stay overnight there is a safe place for me in Southampton
Let me know if you have something available for me
Thanks
