Translation of plenipotentiary in Spanish

The entrance hall where the passports were checked was renovated and had many ads for products from Western countries. Once we passed it and picked up our luggage we were looking for a ride into the city.

Although we shared the ruins with about 3000 other tourists, it still left an amazing impression.
