Well what can you say!! The heat/humidity, the people- so many, the magnificent buildings from Humayun's Tomb so beautifully decorated, to Jama Masjid - one of asia's largest mosques. The simple memorial to Ghandi and Nehru with its beautiful gardens and the Qutab Minar, a tower started in 1199 and rising 75metres covered in the most exquiste stone carving. Delhi is a very green city with many open areas where the people can gather for picnics and celebrations.
We stayed at The Claridges Hotel - a very fine hotel which we would recommend as a base for your stay in Delhi. Visit The Claridges Hotel
