You really shouldn't miss the Ronde Markt in Punda during your stay on Curaçao. The round market is in fact a 'covered' stalls market. You can find the best 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 parking around the Ronde Markt so you don't have to walk far. Although it is definitely recommended to continue walking through Punda after the Round Market.
