Jetsetter "As it happens, the bar (and touted French restaurant adjacent) carries a notable collection of Austrian wines"
Condé Nast Traveler "Spared from total aloofness, the hotel integrates with city life through its design-focused shopping center, while two restaurants attract a local crowd: Le Loft, an airy rooftop restaurant/bar by three Michelin–star chef Antoine Westermann, and Neni im Zweiten, a branch of a beloved Israeli-themed restaurant from the city’s Naschmarkt"
Frommer's "The hotel boasts an unrivaled view from the rooftop Le Loft bar and restaurant, while the gourmet French cuisine and service have a hard time living up to the view, but it's certainly a nice spot to sip from the notable list of Austrian wines on offer"
Travel + Leisure "Locals flock to the 18th-floor bar, with its rotating, multicolored ceiling mural created by Swiss artist Pipilotti Rist"
Star Service "The hotel lacks a pool, but the fifth-floor spa is a spacious oasis of calm and pampering, with five treatment rooms, two whirlpools, two steam rooms, four lounges and a gym"
Fodor's "Afterward, lounge in your plush robe and take in the wonderful view of the city"
