Frommer's
Lonely Planet
Frommer's "51-57); individually furnished with antique beds and chairs, these feature pretty frescoes and block-print fabrics (on rather thin mattresses) and are close to the pool, opening onto a particularly lush part of the garden -- an essential balm after tackling Jaipur's streets"
Lonely Planet "Out back you’ll find a large secluded pool (nonguests ₹300 for two hours between 8am and 4pm), a heavenly spa, and sprawling gardens complete with peacocks"
