You really should not miss the Round Market in Punda during your stay on Curaçao. The round market is in fact a 'covered' stall market. You can find the nicest souvenirs here, but also taste local dishes. There is always a Caribbean atmosphere that immediately makes you happy.
You have several entrances and you have a parking space around the Round Market, so you don't have to walk far. Although it is definitely recommended to continue walking through Punda after the Round Market.
