Hey, I'm Charlotte, university student of English and Japanese Studies in Düsseldorf, Germany.
Charlotte and Laurin were awesome guests and I definitely recommend them. They were so sweet that they brought me nice gifts from Germany, which I loved. Also, they were quiet, clean, respectful, and friendly, and I did not have any problems at all.
I wish I had had more time to talk to them in Japanese.
Hopefully I will see them again next time they come back to Tokyo.
