We stayed at the Le Meridien (18-20 January 2013) and it was a lovely experience. We were put up in a suite with lovely views of the city. The staff were courteous and very prompt at responding or actioning any of our requests. The rooms were clean. If I had to provide a constructive criticism, it would be to do with their showers - the shower frame was a bit rusty which made the shower look a little ugly - but this I am sure is to do with the type of water (too much iron in the water?) which gave it this effect.
I should mention, that I had very little time and could not visit any of the shops in New Delhi, so I bought many gifts at the hotel shops, which I found reasonable priced - so if you are short for time and need to buy gifts don't hesitate to visit and buy something from the hotel shops.
And the breakfasts were great! Shame I can't eat too much for breakfast, but those of you who can, you won't be disappointed.
