Translation of fasten in Spanish

We wanted to take a hot shower but there was no hot water at all. We asked someone to fix it and he showed us that there was a heating switch outside the bathroom which would turn on the boiler.
The city seemed to be small but busy and many building were new. It looked like a third world country village with four and five star hotels. The infrastructure was still bad, but one could see development.
After a while a truck drove by. The driver offered us a ride on the back of the truck. We jumped in. A little later we were back in the hotel, exhausted and hungry. It was time for another great meal.
