Fodor's "This massive hotel is removed from the city's best dining and nightlife options but convenient to the city's historic district and also near the expressway (so it's a short drive to San Isidro, Miraflores, or Barranco)"
Lonely Planet "In addition to 24-hour room service, there are concierge services, two on-site restaurants, a bar, a gym, a swimming pool and a beauty salon"
Star Service "They enjoy complimentary breakfast and evening snacks in the private lounge during certain hours, although, oddly, most beverages (including soft drinks) carry a charge"
