Grand President Bangkok 
Frommer's
Lonely Planet
Frommer's "The biggest disadvantage here (or advantage, depending on your perspective) is the proximity to bars, which mean the corridors are often noisy at night with drunken revelers returning home"
Lonely Planet "Downstairs you'll find ultra-professional staff, restaurants and a lounge area"
