Quick answer
This service matters because it changes how your body experiences the day. Stairs, transfers, station confusion, and timing pressure all become easier when the luggage is no longer attached to you.
Why travelers remember it
The contrast is immediate. Before forwarding, the suitcase shapes the route. After forwarding, the city feels more usable. That makes the service feel almost disproportionately good for how simple it is.
When to use it
Use it when the day involves complexity: airport arrival, multiple train legs, late hotel check-in, or a desire to explore before reaching the next room. That is when it shifts from convenience to strategy.
