Frequently asked questions

Know something we don’t?

OpenStreetMap has no tag for how loud a room is, and almost nobody maps power sockets. If you have been to 15Grams, that is exactly the gap you can fill. A person reads every report.

Reports are checked before they appear, and they are shown separately from the OpenStreetMap data — we never merge them into it. We store no name, no email and no IP address; see privacy. If you would rather fix the map itself, edit the venue on OpenStreetMap and it will reach this page on the next import.

This page describes what OpenStreetMap records about this venue as of 30 July 2026. We do not collect reviews or ratings, and nothing here is a paid placement.
