I live in Tarragona. I thought that is the best city of Spain. Tarragona is placider than Barcelona. The weather is same Barcelona and Tarragona.
People from live in Tarragona are more hapiies, I think, because they are more time for a relax.
Barcelona is beautiful city, there are a see, and a parks. In there strets there are a people with diferents cultures, it's a multi-cultural city.
But when I think to live in Barcelona I don't like it because They are losting the time in transports every day.
