A) That was fantastic and I love to be there.
B) Ah, wouldn't we all ?
To be honest as an intermediate English learner this answer doesn't make sense to me.
would you please explain a bit and make it clear that what is meant here and when it is used.

I assume A is a person who is saying the first line, and B is a person who is saying the second line. I've changed it somewhat below:
Notice that Andrea is using the modal verb "would," and Bobby responds also with the modal "would not." Bobby cannot say Wouldn't we all? unless Andrea has used "would."
Wouldn't we all? is a set phrase that is short for, Wouldn't we all love to live in Tuscany? You can translate it to mean, Everyone would love to live in Tuscany. It's a way of being agreeable with Andrea.
