We were there just for our US Consulate appointments and was very happy that I chose Sona's Inn as US Consulate is just 5-7 minutes' walk from the hotel. Particularly when Chennai was disturbed because of Jallikattu agitations and many road blocks imposed by Police, hotel's location was really great.
Accessibility, Comfort, Stay, Staff Co-operation, Cleanliness, etc. were great. Break-fast & Food was also OK, but maybe there are opportunities for improvement.
