Rough Guide
Fodor's "One of the few solid hotel choices right in Centro, the Windsor Guanabara has reasonably sized and tastefully appointed rooms (although some are beginning to show signs of age), and the contemporary rooftop pool area—with white tiles, white trellises, and white patio furnishings—offers a welcome escape from the city swelter and stunning views of Guanabara Bay"
Time Out "This enormous glass hotel looms out of Centro and is tall enough to offer views of Corcovado and the hills to one side and Guanabara Bay to the other, making the rooftop bar a popular spot for an evening drink"
Oyster "Rooms are comfortable with neutral decor (but awful bedspreads) and they come with a flat-screen TV, minibar, and safe"
Rough Guide "It lacks character but is good value and well run, with spacious guest rooms, a comfortable lounge, a business centre and the added bonus of a pool"
