Translation of corner in Spanish

We bought a Sandwich and were looking for a taxi, but the streets were so crowded that we had to wait nearly one hour to find a cab. We even had to walk a few blocks in order to catch one.
But the fact that our driver took us there before showing us any of the attraction left quite an impression on us. He lost both of his parents in that war which explains why it was important to him.
Many thanks for your letter. I am delighted to tell you that I have passed my exams and am looking forward to the next year. Meanwhile I am planning a trip to Costa Rica and some places around there.
