Me (21 years old) and my younger sister lena (18 years old) are students of econimics from germany. We live in Hanover. Thats near hamburg. At the moment we have semester holidays.
We have never been to london yet. We want to discover london. go shopping, see the sights, the piccadilly circus and an lot more.
We have only a small budget because we are students. Your flat seems to be perfect for a short stay.
