Hyatt Regency Delhi 
Frommer's
Lonely Planet
Frommer's "They're not huge, but the parquet-wood floors, sleek furnishings, and queen-size beds with thick mattresses will certainly make you feel comfortable -- ask for the pool-facing bay rooms, aside from the view, they're a fraction more spacious (but slightly more expensive)"
Lonely Planet "Other hotel facilities include a gorgeous outdoor swimming pool, pampering spa, dazzling shopping arcade, and state-of-the-art business centre that offers translation services (English, German, French and Spanish) and can even print personal business cards in case you forgot to bring yours"
