Since it opened in November 2009, Barcelona's Mandarin Oriental has established itself as one of the city's foremost luxury destinations. Located on Barcelona's most upmarket shopping street, the Passeig de Gracia, this hotel was once the Circulo Ecuestre, a member's club for the super rich. It was also once a bank.
Indeed, the hotel bar (unimaginatively named the Banker's Bar) has a ceiling constructed entirely of safety deposit boxes in a nod to its previous function. Guests can also enjoy award-winning martinis until the early hours after dining at the Michelin-starred Moments restaurant, which specializes in Catalan cuisine.
This 98-room hotel offers a roof terrace, complete with dipping pool, and double rooms start at $450 per night.
