Translation of sapphire in Spanish

We drove to the hotel Rex where we made reservations in advance. However, once there, two American guys told us that they had a voucher from a travel agent and the price was like half of it.
How much Spanish do you know ? My summer vacations were great. I was two weeks in Ibiza, it was unbelievable! We went to the beach and had a lot of party, every night. Now I am back in my little village near Bochum.
And we could not see a thing outside the bus. The bus stopped two hours later at 11pm at our final destination, San Pedro. We took our backpacks and left the bus. The bus drove away into the dark night.
