Translation of austero

In the that time of the year, when I used to go to school, I had to get up very early and leave the house at around seven o'clock in the morning. At this time it was still night, dark and cold outside.
After getting up early I took a local car to get back to the center from where I took a coach to the long awaited city of San Cristobal de Las Casas. I have heard so much about this distant place.
