Bottom Line

The 98-room O'Callaghan Alexander Hotel has a central location on a quiet corner across the street from Merrion Square. Spacious rooms are clean and feature flat-screen TVs, very comfortable beds, and cashmere blankets. However, the decor is on the generic side, bathrooms are basic, and there's a fee for Wi-Fi. Hotel amenities include a casual bar, pleasant restaurant, and tiny fitness center with four machines and an old tube TV. The location is in the heart of the action, with Merrion Square, Trinity College, and Grafton Street all within easy walking distance.

In the heart of Dublin, near major attractions, shopping, and dining

Map of The Alex

The O’Callaghan Alexander is conveniently located right in the middle of the action: it is on the corner of historic Merrion Square and Trinity College is just a block away. Many major sights, including Grafton Street, St. Stephen's Green, and even O'Connell Street can be easily reached on foot. There's a train (DART) station and access to several bus lines down the street, but Dublin is small enough to be easily explored on foot.

This area of Dublin is known for its Georgian houses, historic sights, and great shopping scene. Trinity College, Ireland's oldest university is a large part of this neighborhood. The college was founded in the late 16th century and has one of the most impressive book collections in Europe, including the Book of Kells. The central location of this hotel makes it one of the most convenient picks in Dublin.
