Do you have a SMALL Place I can store a few things?

I'm seeking a space that's CONVENIENTLY located (IDEALLY in Escazu [or Santa Ana - or it could be in San Jose] - accessible by bus), safe, dry (not moldy), where I can store 3 suitcases, a duffel bag, 1 of those big plastic containers (it has a toaster oven & a few other things in it) & I think it's 3 other plastic bags (2 with shoes) & that I can get to maybe once a month or so. 

It's for ME (Vicki the "Sarong Goddess") to keep "ALL my things" at while I'm out & about traveling around Costa Rica doing House, Pet & Hotel Sitting. 

IDEALLY FREE or MEGA cheap!!! 

(I'm open to "trading" for some Marketing advice, Pet/House Sitting, Facebook help or ?????)
