I lived my best years in India. Delhi is more vibrant than Rome, with book launches, research centers, and art galleries everywhere. It was a heaven for me. Oh, don't forget the Biryani in Nizammudin. If you want to see natural places in India, visit northern states like Kashmir, Nanital, or North East. Old Delhi, Jaipur or the Taj Mahal does not represent the whole of India. However, if you are interested in history, these places would also be cool to walk in.
