Comments over the JW Marriott hotel:

Lonnely Planet:
The newest five-star addition to Miraflores, the enormous Marriott is perhaps the flashiest of them all with a superb seafront location by the Larcomar shopping center. The sparkling rooms seem to have every amenity going, including temperature regulation and no less than three phones in each room, and there are glass-fronted restaurants and bars, a large casino, plus an open air-tennis court and pool. Rates do not include breakfast.

By Fodors:
This isn't a hotel - it's a small city. Just about anything you long for, whether it's a chocolate-chip cookie or a pair of diamond earrings, can be had in the shops downstairs. If not, there's the Larcomar shopping center across the street. The views are spectacular from the glass tower, which forever altered the skyline of Miraflores when it opened at the turn of the millennium. On clear days the entire coastline is visible. The only disappointment is the rooms, which are luxuriously appointed but lack the slightest hint that you're in Peru. The Stellaris Casino, one of the city's most glittery, is a winner

By Moon Handbook:
Across from Larcomar shopping center, wonderfull views from its towers, pool, fitness center, two restaurants.
