Yep, my brother used to work out there. Only been to Tunis and the Carthage area, though.
I stayed near a small town called Marsa. If you need your hand holding when you’re on holiday it’s probably not for you since very little English is spoken. You can (just) get by in French, and I learnt the Arabic equivalent of “Bugger off” for the street vendors.
I don’t think you’d want to go for longer than a week. Temp was about 30C in September when I went but started dropping rapidly. In fact the drop in sea temperature was noticeable over the course of 7 days.
Definitely off the Eurozone, definitely not on the beaten track but great fun. Driving is erratic but not particularly dangerous. Food is VERY nice, since any seafood is fresh and there’s a lot of Italian influence.
