If you are looking for an ideally located place in Chennai for a quick business trip, I feel Metro Manor is the place for you.
From the Central Railway Station it is 'walkable distance'. (this will depend heavily on what distance you are willing to walk. It is less than two Kilometers if you choose to walk.) Picking an Auto will not be a bad option if you have too much of luggage. But, my experience in that city is that you must settle your charge before you enter the auto. The reasonable charge is said to be Rs. 30. You may face with demands much higher than that - My highest metered is Rs. 70.
The rooms were neat. So were the toilets. For Non A/C Accommodation for two with complementary breakfast was only Rs. 1000. That sounded pretty reasonable. And yes, the breakfast was not just complementary, but also one which deserves complements.
But the Buffet Lunch for Rs. 200 was a disappointment. Every thing was a bit too spicy than necessary. But then some one wanted it to be titled Chettinad Lunch. But how is Chettinad Lunch having Chilly Chicken, with more chilly than chicken is yet to be discerned. But I must record that this opinion of mine is very personal, as I do not like very spicy food. Some one may like it.
Also, I must state that I did not (yet) stay at the Hotel for a night. My chennai business trips are mostly lasting only one day. I reach in morning and leave by evening train. But I did spend almost half a day, (Flat 12 Hours) at my room last time and thought that entitle me to write a review. :-)
The service was good. Food was reasonable. Finally, the rates were honest. I liked the place, and give it a 3/5. (am a bit miserly there.)
