Renaissance Hotels in Nanning

Overall the hotel is well organzied. Only staff not smart, careful and not detailed in mind. My stay extended one day, since cannot change the original booking (a 2 days stay), I made another one separately. Upon check in, reminded reception, and the gentleman did arranged my check in through out entire 3 days. Unfortunately, the assigned room at 19th floor (?) has bad smoke smell, thus I requested a change of room, at first the customer service lady on phone asked me to open window, and giving different kind of excuse and tried to refuse my request, after much request, she said she will arrange and will can me back. Which took 15-20mins and still no return call for updates, until I called again and finally got a change of room to 18th. another 2 bad experience were : 1) after changed room to 18th, only 2 days being arranged and on the 3rd day when I returned to room, my card was disabled and I had to go down to reception and got my card reactivated, where the girl did challenged me about my booking, said it's no record showing that I have 3rd day booking... 2) my booking is executive room, with free lounge service, after being moved to 18th, I am not able to access 19th to enjoy the lounge, and, I had to go down to reception, again... for the rest, overall service is OK, and the lounge is great.
