CRISIL Ratings has upgraded Robust Hotels Limited's long-term rating to 'BBB+/Stable' (from BBB/Stable) and short-term rating to 'A2' (from A3+) for its Rs. 170 Cr bank facilities.

The upgrade reflects a sustained improvement in business risk profile, driven by higher average room rates and operating margins at its Chennai property.

Strong financial health and comfortable liquidity also supported the positive change.
