After 2.5 theme update
NOTE: No matter the theme options, users will stay on the same page if they login from Property page (for users to stay on the same page to complete booking request) and they will be redirected automatically to Edit Listing in User Profile if they login from the Submit Property template
You can tell where users redirect after login from theme options
Or you can choose users to stay on the same page after login
