View from a window at U Maleho Glena pub. This is a pub really close to Prague Castle - actually being right under it - and Charles bridge. There are music concerts at the underground hall (it is a famous jazz and blues music club as well). And if you go there you'll see photos on the wall. Those are the photos of a friend of mine. Unfortunately I haven't been there nor see them. I was only at the upper pub enjoying the old Prague atmosphere here - with a glass of not Czech beer.
You can rent a room at U Maleho Glena also. I would say you can hardly find better placed accommodation in Prague than this one.
