If you're in this price bracket, don't waste time looking any further than the bright, friendly, efficient Le Roi, right beside the station. Spotless, good-sized, pine-accented rooms have good wi-fi, good air-con, tea/coffee facilities and up-to-date bathrooms where it's a delight to step into the shower.
There's a 24-hour restaurant and coffee shop too. Airport transfers ₹500.
