Lining the coastline is a promenade known as the Sliema Front that has become the ideal spot for joggers and walkers as well as a prolific meeting place for locals during the summer season. Romantic moon strolls, barbeques and open air restaurants and cafes have made Sliema the hub of social nightlife. Sliema is also known for its numerous rocky beaches, water sports and hotels.

Sliema, which means 'peace, comfort', was once a quiet fishing village on the peninsula across Marsamxett Harbour from Valletta and has views of the capital city. The population began to grow in 1853 and the town was declared a parish in 1878. Now Sliema and the coastline up to neighbouring St. Julian's constitutes Malta's main coastal resort.

Sliema is considered a desirable place to live and is relatively affluent, with extremely high property prices compared to the national average. Historically, stylish villas and traditional Maltese townhouses lined the streets of Sliema. Sliema has now been ringed with modern apartment blocks, some of which are amongst the tallest buildings in Malta. This has resulted in significant traffic, parking and construction-related noise pollution issues.

Residents of Sliema are stereotypically known for their usage of English as a first language, although this is changing in the 21st century due to demographic shifts. Maltese people from Sliema are referred to as Slimiżi.
