We flew WizzAir in August of 2019. Staff at the gate allowed us to pre-board, and the flight attendants were extremely helpful. They made three announcements (each in English and Hungarian) asking people not to eat peanuts, and gave us seats together for free, in the unlikely case we had an emergency and needed to use the Emerade pen.
They let us board early, and in fact moved our seats once again as there were spilled peanuts, which was extremely helpful of them. They even offered to help us clean our new seats.
I would fly them again and was appreciative that the flight attendants were extremely helpful.
