One disdadvantage of the centre of Vienna is that in recent years rents have risen greatly, and most of the shops that formerly sold things that I might be able to afford, have been replaced by Fifth Avenue/Bond Street/Champs Elysées chain stores like Chanel, Gucci, Louis Vuitton, Armani, etc. Even in the side streets, prices are amazing.
Yes, these little animals are interesting: they are made of glass, mirrored on the inside; but at prices around €5000 each I'd be afraid of breaking one.
Even €1200 seems a little excessive for a piggy bank!
