Big Ben, the Coliseum, the Eiffel Tower — all landmarks you can find with your eyes closed. But there are even more exciting places, and London, Rome and Paris all feature plenty of out-of-the-way beauty.

We start with Berlin, a city whose quirky charm is exemplified by the Propeller Island City Lodge, a hotel -- no, a work of art -- with very special rooms.
