3-4 days might be ok, but it is sad to try and see it in a day!

My last trip was the first time I had been to the Franz Kafka Museum. Worth it to see the fountain. (hah!)

We love the food and the people. The Marriott is a short walk from the square. There is a great park where the former huge statue of Stalin sits overlooking the river. In it's place is a massive red and black pendulum sculpture. Neat place.

The old town Hilton is across the street with a very good restaurant should you have to eat hotel food. It is a Gordon Ramsey joint....but I strongly recommend going local. So many great places.

Hint to improve how much you enjoy yourself. Pretend the Euro equals one dollar. Trust me, while you are there it will feel much better. Maybe not so much later.
