Everything was good. Once when I returned to the hotel and I needed my key card for my room, the night clerk was on the phone and did not understand that she should give me my room key NOW, while she was talking. I waited patiently for a time, then motioned for the room key.
Also, when I first arrived, the porter did not show me where he put the room key (in the energy saving card pocket by the door). I searched high and low for half an hour . . . thinking that it was in my pockets or on a table . . . before I spotted it near the door. Some 3 star hotels in Vn have this feature, some do not. I had only seen this once before. He could have save me some agony by just pointing out where he was putting the keycard.
Otherwise, the staff helped me learn a few words of Vietnamese and was very responsive.
