Office space or room to rent with internet

I will be arriving at the end of February and staying for a month in Conil De Le Frontera.

I had been researching broadband and having it installed in my apartment but have been let down last minute by a company you've said it can't be installed due to historical building and the town hall not allowing it.  I tried other companies without success.

So I was wondering if anybody quite local to Conil either had a room they could rent to me to work from, I would just need internet and I have own phone and laptop etc. Or if they know of any cheap office I could rent?

Many thanks
