Pohjoisranta Marina

Pohjoisranta puts you right on Helsinki's northern city-centre waterfront, steps from the Senate Quarter and the old market hall. It's a full-service guest harbour with berths, so you're not roughing it — showers, electricity, and all the basics are covered. From the dock you can practically walk to everything: cafés, museums, ferries to the islands. Hard to beat for a central Helsinki stop.
