Non-lucrative Visa - visado de residencia (Barcelona)

Hi there, Just arrived in barcelona and I need to get my permiso de residencia with the non-lucrative visa that I got in the US. The consulate didnt really give me much information on where to go and what I need to bring with me. It was a tiring process to finally get the visa so hoping you guys can save me some pain and let me know exactly where I need to go and what I need to bring.

Thanks!!
