About Dublin
Ireland's compact capital combines Georgian architecture, a world-famous pub culture, and a literary history that runs from Swift to Beckett to Heaney.

Where to stay in Dublin
How the main neighbourhoods compare, based on trip type.
- Temple Bar / City CentreBest for first visit
The area on the south bank of the Liffey between Dame Street and the river is the most central base for a first visit. The location puts the National Gallery, Trinity College (Book of Kells), Dublin Castle, and St Patrick's Cathedral all within a 20-minute walk. The streets around Grafton Street and St Stephen's Green are calmer and more practical during the day. Temple Bar itself is very loud on weekend nights - addresses on the south side of Dame Street facing away from the river are significantly quieter for sleeping.
Metro: DART (Tara Street), Luas Red Line (Jervis) · Airport: Aircoach or Dublin Coach around 30-45 min depending on traffic · Tourist-facing, central, noisy on weekends
- Smithfield / StoneybatterBest for a weekend
The neighbourhood northwest of the Liffey has a more authentically Dublin character than the Temple Bar area. Smithfield Square hosts occasional markets and the Jameson Distillery is on the square. Stoneybatter to the northwest has a strong cluster of independent pubs and restaurants that cater more to local residents than tourists. The Luas Red Line from Smithfield to the city centre runs in under 10 minutes, making it practical as a short-stay base.
Metro: Luas Red Line (Smithfield) · 5-10 min Luas to O'Connell Street · Local pubs, market square, authentic
