This seems pretty reasonable to me. Unless they seriously expect you to not use the kitchen or bathroom, then that’s insane. I’m a room dweller anyway and $500 is hella reasonable (unheard of where I live), so that’d be an ideal situation for me. Hell, even if they didn’t want me using the kitchen I could still make die because the money I’d be saving on rent could go to DoorDash every night. The only dealbreaker would be if I had to shit in a bucket.
