Concierge.com's insider take:
Decked out in Louis XVI revival decor with a touch of Nordic Art Nouveau, the Grand Hotel has been an Oslo institution since 1874—in the early 20th century, Edvard Munch was a regular at the hotel's Grand Café. The self-consciously elegant ambience in the public areas (chandeliers, crystal sconces, tapestries, and ornate mirrors) carries into the 290 guest rooms, which are dressed with flowing floral curtains and polished parquet floors. The Tower Suite, a romantic triplex that rises above the hotel's rooftop, is a good bet for honeymooners; there are 13 rooms specially designed for females on the Ladies Floor (although gentlemen are permitted to stay in these rooms as well). A gorgeous Scandinavian-style spa opened on the top floor in 2007.
