Probably not. If a superhero's "base" is meant to be an extension of the superhero, then I would expect Wonder Woman's base of operations to be some kind of sanctuary which welcomes all visitors and anyone in need of help. Maybe even a homeless shelter. I'm not sure how it would work exactly - perhaps a portal to a small slice of paradise where people can get warm, get clean, eat some food and then be on their way again?
I guess an official Themysciran Embassy is the closest concept that I can think of. Somewhere anyone is welcome to come in the event of need. It operates somewhat as a philanthropic / charitable entity, but also as a place for people to come and petition Wonder Woman's help in current world events (e.g. to help broker peace between two warring nations). It would be protected magically so that no harm can come to those who enter its boundaries. And it could house a number of Diana's friends and rehabilitated foes.
A Themysciran Embassy is probably the closest to a "base of operations" that I can think of as being appropriate for Diana. I guess, basically just a return to Themyscira House (and associated embassies worldwide):
