There are lockers I'm not sure about the Greyhound bus I'm not even sure the Greyhound bus runs through Santa Monica anymore I have a car so on this is why I have no idea but anyway I'm sure you can take showers there and I'm sure there's lockers for you to lock your stuff up in
1751 Cloverfield Blvd. Santa Monica, CA 90404
I don't know how far the Greyhound station is from there I know the closest one I know of is downtown Los Angeles the shelter you have to go into their emergency shelter first if you were a woman and the man I'm not sure of they do have a day Center but there are no lockers to store your things
