I was in hamburg on the 6th May! This time not in the center, but in a district which is named Blankenese. There we walked hundreds of stairs, because the dirstrict is the "Treppenviertel" (Stairs quarter).
We visited two cool cafes, with an amazing view on the Elbe river.
It was cold and we just stayed up to 4 hours. Another reason for the short stay, was that my little sister has a strain, so she couldn't walk so fast and far!
