We took this flight as part of a trip to Crete reserved through a tour operator. After an information breakdown in Roissy that caused an hour delay, boarding was quick.
The plane was barely clean (crumbs and balled up paper in the seats), uncomfortable, terrible pressurization, loud, horrible heat and no TV or other entertainment (nothing for children). All we got were the seats and a tray table, with no legroom (I'm 5'4"). The flight attendants were sulky. They talked to each other and didn't seem to care about the passengers. We got a bad sandwich and a glass of something to drink. I had to beg for a glass of water for my sick daughter, they didn't pay any attention to her.
Toilets were run-down and barely clean.
Takeoff and landing were rough and hard on the ears.
On the return, the airline also had an hour delay, with the same explanation for for the flight conditions. We hadn't wanted to travel on Ryanair, but we should have since the service is the same but the cost is less.
