Former San Diegan here (moved to AZ in May). I believe that Anton has re-opened, but by appointment only (I think he mentioned on his Facebook feed). I'd call the Rollov Film Center directly, he may not have updated the website yet. You may also want to check with San Diego City College I heard through the grapevine that they were attempting a deal that didn't require enrollment in classes (YMMV).

The house I left in La Mesa had a 1/4 bath with about 19.5 sq. ft. that I was able to fit a D5500 and trays for 8X10. Useable but cramped. Good luck!
