Translation of sublease in Spanish

We could not believe how difficult it was to find a decent room in this four star hotel. I went to the reception desk and complained about our room and about the attitude and bad service.
I bought some food also for the next day, where we planed a trip to the Angkor Wat. I returned to our room and picked up my fiance. Sammy was already waiting in the lobby for us.
We checked in at the Hotel de Paris, a small hotel owned by a friendly, old lady. Our rooms were OK, but we asked to be transferred to the newer part of the hotel. The stomach ache of my wife did not disappear.
