why not try a reputed guest house instead of a hotel..
u can stay at Chalet Guest House which is located in places like defence, boat basin and near forum..
it costs around 3500 rupees for a night stay..

u can check for their rates by yourself..
this is a real nice place as few of our foreigner guests stay at this place..
if u are talking about hotels, Ramada Plaza Hotel is an excellent addition.. charges were 6500 for single person for a night stay back in January 2009.. u can check their tariff too..
have safe journey..
