Translation of struggle in Spanish

When we got our room at the Rex we were shocked once again. The room had a terrible smell of cigarettes and we insisted on moving. The next room they gave us was a non-smoking room.
thanks for the compliment! Can you understand me when I write in English? Spanish sounds so beautiful when spoken. I would really like to be able to speak Spanish fluently, since I am planning a trip to Peru.
A band was playing Peruvian music while we were waiting for our luggage. The altitude is immediately felt: Dark blue skies and thin air, which won't let you climb stairs without having to take a few breaks.
