I've been four times also, after it became my favourite place in the world, due to the Cuban people. I would have loved to be able to stay there, maybe working there, but as you can probably guess it's more or less economically impossible. Western banks won't allow any business at all with Cuba, I wanted to do business assisting Cuban dance companies with technology but my UK bank froze my account leaving me high and dry in Cuba, with relatives having to get me out. That was in 2019. I haven't been back since, but would go in an instant if economic circumstances changed around they way they need to, for sustainability.
