Room sought - V short term

Hi. My landlady has decided to sell & given me notice to move out… Also, my work place is relocating & I’ve no wish to follow them.
My plan is therefore to move permanently to Gloucester but I just need to scrap some savings together first.
Therefore, I’m thinking about finding somewhere cheap to stay for a few weeks (month max) before I make the leap.
Ideally in SE area. With or without secure parking, depending on whether there’s good bus links. I may move the bike over to Gloucester early. Single room or similar is fine. I have no possessions to bring.
Mature, no smoking & I work nights so apart from needing a key to let myself in around 4am, you wont even see or hear me.
Timing around 6 Sept. Can provide references/proof of forwarding address. Rent up front etc.
