Where in the world are we?

Here are some clues. The answer and pictures will be posted later.

• There are about 1 million people living here and over 170 different nationalities
• The city is home to about 700,000 bicycles, about 80,000 of which are reported stolen each year
• A scene in Ocean's 12 was filmed along the canals
• There are over 60 miles of canals here, with over 1500 bridges
• The canals are about 9 feet deep, with 1-2 feet of 'disposed' bicycles...luckily they dredge the canals every year!
• Nearby attractions include ancient Roman ruins, a town dedicated to cheese, a 70 acre botanical garden
• It is quickly becoming one of the most expensive cities to live in
• Prostitution is a career for some women (they pay taxes!)...and they have a specific 'District' that they work in
• You can 'tip-toe' through acres and acres of fields of my favorite flower

Any guesses?
