So indeed not a good experience of hotels in Vietnam. After a couple of nights realised the bites in arms, legs, neck were caused by bed bugs. Reported the matter at the reception. Saw staff take any cursory measures (superficial cleaning) so continued to suffer from bed bugs. The cleanliness of the room looked ok on a cursory glance - however e.g. the bathroom floor tiles showed no evidence of proper scrubbing for a long time (were black in between the tiles when in fact the original colour had been white). English skills of even reception staff were rudimentary. Not worth the money.
