Comments over the Sheraton hotel:

Lonnely Planet:
Four hundred typically comfortable and spacious Sheraton rooms are housed in this vertigo-inducing, boxy tower overlooking the Palacio de Justicia. There´s a Visa ATM, and a casino to spend your freshly withdrawn cash in.

By Fodors:
The country's largest casino can be found in the lobby of downtown's most distinguished hotel. You might call it a landmark, except for the fact that its concrete facade makes it fade into the background. Perfectly serviceable rooms have subdued colors and surround an open atrium. This is a good choice for business travelers, as it has eight large meeting rooms and a convention center. Tourists appreciate that it's within walking distance of the city's historical district. The hotel is near the expressway, so it's also a short drive to San Isidro and Miraflores.

By Moon Handbook:
A 5-star hotel located on the edge of downtown Lima in an imposing building with large casino on the ground floor.
