Not long back myself and have to agree with the other Steve, absolutely loads to shoot.
Vittorioso ( also known as Birgu) was my favourite. Little lanes with no cars and the light was amazing. Plan to go back next year I enjoyed it so much.
We didnt have a car but the bus service is excellent, an all day ticket is 2.6 Euros and the busses seem to go everywhere.Maraxlokk in the south is another spot I would recommend, a very picturesque little fishing village and Mdina as previously mentioned is well worth a visit.
Camerawise , I used my X100 most of the time only bringing out the X10 on a few occasions for the longer shot.
I'm sure you will love it.
