I stayed in CDH in two parts. In my first stay I was allotted 6th floor which had no lift (lift available only till 5th).had to struggle my way from 5th to 6th with out lift with my heavy suitcase and bags. This shared room was not clean as well.
Also as I stayed in two parts in CDH, I had to keep my big suitcase in locker for my travels to other cities. I lost my stuff's in my suitcase case as i found it outside the locker when I came back after 8 days. I had clearly requested the staff in reception to move my suitcase from x9 to x3 (I had accidentally kept it in wrong locker as I was in a hurry to catch my flight), which they had promised to do but it was never done and I ended up loosing my valuables. They did refund back the locker charges and to an extent the value of items I lost however the experience was bitter. The room I stayed second time around was much clearer.
The location of CDH is excellent, the bar downstairs is also vibrant.
