Flying to Oslo
I've arrived in Oslo with 'Norwegian Air Shuttle'. It was my first time flying with them and the trip was very pleasant!
The train ticket from the Airport to the Oslo City centre via 'FlyToGet' was 240 NOK (around 20 Euros) in one way! At least the train is reliable, fast (~20 minutes) and frequent.

Aker Brygge
Fjord Cruise
I've booked the 'Scenic Fjord Cruise' with 'GetYourGuide' a couple of days before my arrival. The price was 30 Euros, and the cruise lasted about 1.5 hours. It was very cold, windy and rainy. So, if you are planning a trip in this time of year, always bring your full winter gear (coat, gloves, scarf, beanie, etc.).
