I am in Hamburg. Before coming, I did a Google images search, and the results looked dreary and cold. It looked like a sterile port. For example:
But the city is actually gorgeous! The buildings look very well-preserved, and downtown is located right next to a peaceful lake.
I felt refreshed just from walking to my hotel, dragging my luggage after a eight-hour train ride from Prague.
My hotel told me they were giving me a free room upgrade. The room looks nice, but just like the standard room on the hotel web page. If I were running a hotel, I would tell every guest that I'm giving them a free upgrade, just to make them happier. I would keep a broom closet as the "non-upgraded room" so that it is still truthful.
