This was my first experience of using Hop! and on the whole, they were very good.
The plane was an Embraer 190 and it was quite basic - which vinyl seats - but the legroom was file and it was clean and tidy.
The staff on-board were very pleasant and efficiently sorted out a snack and drink in the 1 hour 20 minutes that it took to get from Newcastle to Paris - along with their other duties.
The snacks were fine - I had a chicken wrap, but I'd go for a bottle of wine or a can of lager if I flew with them again just because you only got a small glass of water, juice or a soft drink if that was your preference.
There was no on-board entertainment that I could see, but for a flight this short, none was required.
