Frommer's
Star Service
Frommer's "All this would be nothing without comfortable and clean rooms, and those are fully kitted-out and don't disappoint: big beds, minibars, central AC and heat"
Star Service "The lobby opens onto a vaguely triangular lounge area where a guest-services representative meets personally with each new arrival to answer questions and offer sightseeing tips"
