The Grand Hotel Du Midi, Montpellier, which is the triangular pointy end of a city block. (Technically, I suppose it's a trapezium, since they just nipped the point off for those balconies, but let's not quibble...) It makes for some quite interestingly shaped bedrooms - I was one room along from the pointy end, and distinctly not living amid right-angles for my stay! Also, I love that kind of Railway Age confidence that puts your hotel name in Art Nouveau script and gold like that.
