Finding reasonablely priced office space

Can anyone recommend any reasonably priced office space in London, preferably south east, but if not anywhere in London, or Bromley (Kent) area.

basic requirements are, clean space, cleaned daily. Ability to bring own computer, monitors, secure.

just for 1 desk

Thanks

 

It is getting much more complicated when you are in search of a proper space outside the country. I am about to move to worldpostalcode.com/united-states/california/sacramento and now I am researching the local commercial property market, it's really tough when you do it remotely.
