guys! We have web-portal and there is a filter "near subway station ...". So I am curious about what "near subway station" means specifically for you? 50m, 100m, 1km, 2km, 10km and so on? Thanks for your feedback!

Many good questions generate some degree of opinion based on expert experience, but answers to this question will tend to be almost entirely based on opinions, rather than facts, references, or specific expertise. If this question can be reworded to fit the rules in the help center, please edit the question.
I think this will depend on the general availability of subway stations for your users. In general how many subway stations exist within a 50km radius? If several, then 50km could serve as "near" for the users.
"Near" should serve the purpose of showing the "n" closest stations. You certainly don't want 0 to be the result, and ideally would not want more than 5-10. A study of the distance between subway stations would yield this answer.
