Buses from Slussen, follow the signs towards the area of Nacka.
Bus stop : "Långsjöstrand" (two bus stop after Nacka Forum). Half arrows to the On Inn.

Even if you don't come by bus you will need to bring a SL-card for the run.
No sauna, but there's a shower so...

Please let us know if you're coming so we can plan food and drinks.
