When I arrived her house, she was in Denmark, so she sent her friends to give me the key and the information - the oven instruction, towels, bedrooms, etc. Actually she didn't need to do that, because she remained a letter(full 4 pages) and it let me know everything enough. Her friends were also very kind. I needed to go to the station at the next day in very early dawn, they tried to help me that I could use the bus. Her house isn't very close to the central station, but it's walk-able distance.
