Stayed in Sliema a couple of years ago when England played in Malta. Not a bad place but good for the short ferry to Valletta. Valletta is lovely with lots of historical things to see. If you like a beer then visit "the pub" which is where Oliver Reed supped his last pint. A visit to Valletta will easily eat up a day. St Julians bay is good for a night out. Malta is fabulous and they still love the Brits over there.
