Frommer's
Fodor's
Frommer's "The young, diverse staff can tip you off to new restaurants and bars and find a professional to look after your children while you explore"
Fodor's "An in-house cafeteria serves coffee, tea, and pastries around the clock, but a number of bars and cafés in the immediate neighborhood are more inviting"
