It's very pretty with a great beach, and lots of restaurants and bars in the narrow lanes and along the waterfront.
If you do catch the train, make sure that you know when the last one back to Barcelona departs from Sitges, which is usually about 10:26pm.
There is a night bus which leaves Sitges to Barcelona from in front of the Oasis building by the railway bridge - look for the Mon.bus sign. It's the N31 bus, and leaves at 01:36, 02:36, 03:36 and 05:16 - more details on this Mon.bus itinerary.
