Budapest is one of Europe's great cities, in my opinion nicer than Prague (which is still beautiful). The panorama of the Danube especially, with the magnificent Parliament on the one - the Pest, or new town side - and the Castle Quarter with its scores of interesting buildings on the other, the Buda or old town side, is simply a great sight to behold. Also the inner city with the Andrassy Boulevard is a wonderful area for a stroll. Budapest is of course very easy to reach from Austria, and a popular weekend destination, but if you have the chance to see the city, even if you are from further away, you should do so.
