I stayed in Hotel Planet Mount when I was in Chennai in the first week of May 2014 for my visa interview. It is a great place to stay under a budget. The place is a few minutes away from both the consulate and the OFC center. The staff are very friendly and kind, and the doorman often helped me find auto and set fair prices with them. Rooms and accessories are clean and well maintained. The room service is pretty good, and fair priced. I would recommend this hotel to anyone travelling to Chennai for two days for the visa.
