I am not a huge fan of business hotels, so it is a rather biased view that I present. But then since I travel most months a year and stay at these hotels, I sure can benchmark it.
I did like the breakfast buffet, but otherwise the room service food from the restaurants was rather insipid. I would presume that the tastes were blanded out to suit tastes of visiting foreigners, but it was rather poor food by Delhi standards. You'd expect better food in Delhi, for sure!
The room was quite comfortable, but not very well maintained. Some of the furniture in my room looked rather worn and scratched. The sofa in the room looked like it hadn't had a was in a long time. The ironing board was dirty and the iron itself had a burnt bottom which ruined one of my shirts.
i did not avail too many of the facilities in the hotel bar the room service, as I had a rather heavy schedule, so cannot comment on those.
Though, it was not too exorbitant, one expects better facilities at a Marriott.More
