You would need to be a bit more specific, as that will depend on your preferences. If you're looking for warmth and beautiful beaches, go to the Balearic Islands. If you're more interested in gastronomy and a somewhat cooler climate, Galicia is a good option.
My opinion on dropshipping is negative, regardless of the country. Regarding VAT, assuming you're referring to applying for it in Spain, I can tell you that it's a very simple and relatively quick process.
Well, the truth is that this is going to sound really bad, but I don’t have many good things to say about my fellow countrymen. The average Spaniard is an ignorant person, quick to get outraged and take to the streets to break things over any football event, but when it comes to defending their rights, they prefer to stay home and, if anything, complain on Twitter about how badly everything works. It’s sad, but true.
I feel much more closeness and empathy towards Latinos or people from Eastern Europe than towards my own countrymen.
