They actually gave us a bar voucher at check-in, which I thought was great.
Went up to the bar to get a drink before dinner, was told it was happy hour thus cannot use the voucher, but only after they served the drinks despite announcing I was using the voucher during my order.
No problem, went for dinner, came back for more drinks after dinner, and after serving my beer (opening the cap) then telling me I can't use the voucher again because voucher is not applicable for beers, despite again having informing the bartender I'm using the voucher before ordering. This guy is really crooked. I guess the empty bar should have been my first hint not to patronise the hotel bar.
The room had no windows, but this seems like a regular thing in Hanoi. The cleanliness was not up to par which was surprisingly tho. Bathroom shower fixture also had issues.
