On the plus side:
Doubletree Chongqing is conveniently located in a busy and vibrant district, with a lot of choices for restaurants and eateries within walking distance. Most taxi drivers know about this hotel except for one taxi driver we met and we had to hail another cab.
The service at the breakfast buffet is one of the best in China. Very attentive service and the staff can serve you eggs and noodles if you wish. Excellent coffee which is a rare genre in China.
The chocolate cookies upon check-in are a nice touch.
On the down side:
We booked two rooms through the airline holidays (CX holidays) and strangely they couldn't find the booking of my parents. It took a bit of time to check-in considering we were a bit exhausted from travelling.
My father brought his belongings to their gym and pool during our 2-day stay but was told at the gym entrance that BOTH the pool and the gym were out of electricity and out of use, which we were quite shock to learn, considering that it is a hilton group hotel and we are situated in a luxury shopping area and the electricity in our rooms and our area just worked out fine. Also, there was no advance warning given to us at check-in or our stay. Gym and pool access are the basics of a high-end hotel.
When I booked the rooms I specifically choose the free wi-fi option through the airline holiday package (while the booking for my parents was cheaper and did not come with free wi-fi). The staff at the conceige denied that we were entitled to free wi-fi even after I showed them the booking confirmation and the airline holiday website which specifically lists the wi-fi benefit. They asked me to check with the travel agent directly in Hong Kong (at 5pm on a weekend which I am sure nobody would answer). In the end they waived my wifi charges but it was not without some arguments and frustration.
