AY412 would be my first turboprop plane in over 30 years! The last time (and also my first) was back in 1986 on a Fokker-27 (which was not something I was fond about). I vaguely recalled the flight being almost like a roller coaster.
ATR-72 is a completely different bid from what Fokker-27 was. Although small and flying in the winter, the plane was fairly steady. The plane is single cabin and configured in a 2-2 seating.
Similar to my previous flight to Rovaniemi, food can be purchased on-board but non-canned beverages are provided FOC.
One board the plane from the rear, hence I would suggest to select the rear seats rather than the front seats. However with only 72 person at max capacity, one will get to deplane fairly quickly.
The flight I was on unfortunately had no water supply from the sink. Packets of hand wipes were placed in the sink for use.
It was a quick and uneventful flight. Although small, the flight was fairly stable. The only thing is the noise from the turboprop engine can be quite deafening.
