The best Helsinki tour guide

My name is Niki Keinonen and I’m the Chief Experience Officer at One Day in Helsinki. The idea for One Day in Helsinki was born out of my passion to create amazing experiences for people visiting my hometown. I’ve lived most of my life in the Helsinki area, but travelling to over 40 countries and living abroad in Germany, USA and twice in China has widened my perspective of the world. I really enjoy being a private guide, so I guide as often as I can. The best Helsinki tour guide at your service!

Petra Rosvall is my sister and the third founding partner. She is our coach in all things human. We design experiences together to create perfect tailormade experiences.

At One Day in Helsinki what matters most to us, is that you get great vibes and a day you will never forget.

We are now accepting private tour enquiries and bookings for 2026 and 2027.
