Fabianinkatu 1, 00130 Helsinki

HELAXE is located under Tähtitorninmäki (Observatory Hill), about a 10 minute walk from the Central Railway Station. The address is Fabianinkatu 1, where Fabianinkatu ends in a ramp that leads inside the hill. There’s a sign that says EuroPark on top of the entrance to the ramp. There’s a set of heavy doors in the ramp with a smaller door, just walk through that and you should see the doors to HELAXE. 

If you’re coming by car, you can drive into the Europark garage through the side of the ship terminals on the other side of the hill. The gate is located at Laivasillankatu 20. Parking costs 5,60€ for the first hour and 2,80€ for each starting 30 minutes after that.
