We (two adults, one teenager) had very limited time in Helsinki and wanted to see as much as we could, and so seeing all the great reviews online, booked a 3-hour cycle tour with Karri. The booking process was great - Karri was friendly and answered all our questions, and guided us through what to expect and where the tour was in relation to our hotel. The bikes were smooth and great to use, and the cycling infrastructure in Helsinki was great - we really enjoyed the tour and felt safe on the roads throughout, despite not having cycled in the city before. Karri was friendly and knowledgeable, telling us all about the history of the city and buildings, and stopping at some great spots for photo taking and refreshments! He has great energy and we had an amazing time, feeling like we had made the most of our overnight stay in the city! We would highly recommend!
