People come to Dordrecht to work or for the history of the place. If culture's your thing it's a very interesting, and pretty, place to go. Average shopping (although lots of small art galleries and antique shops) and passable but unexciting nightlife.
There are some districts that are very beautiful. I live here myself. A lot of green and water (view photos). They sometimes say the closer you get to Dordrecht the worse it gets but my opinion is that once you're in you'll have fun.
It is pleasant to shop here with the friendly and helpful employees and the longest shopping street of the Netherlands! Visited a nice church and a lot of monumental buildings. The nightlife was very pleasant, no hustle or whining!
