I have spent 5+ weeks in the Trident Hilton and would absolutely stay there again.
The rooms are amazing, beautiful (get a pool view)! The hotel is very quiet. Sometimes, it feels a bit lonely compared ot the hustle and butstle of 4 and 5 stars in the Delhi area.
I got very ill, not from the hotel, and I felt like I was at home with how well they took care of me.
