Mor Bhavan is a good place to stay. Its decent and in budget too. Ask the Car parking caretakers for the way if you don't know. Helpful people they are
The Ultimate place that's a symbol of Goddess Radha's love for Lord Krishna n various stories of them, historic too. A city of temples, officially has more than 5500 temples. U'll hear Radhe Radhe :-)
Do visit Banke Bihari Temple, Prem Mandir, Iskon Temple, Ranganathan Mandir and few more places but beware of Panda/Pandits. They will ask you to show 51 temples for Rs. 51 or so. DO NOT HIRE THEM.
