British, couple in early twenties.
Generally the hotel was beautiful, nice rooms (although no balcony), extremely clean, not too far from shops and bars, breakfast we were spoiled for choice and the hotel staff are very friendly.
The hotel lobby was very pretty, nice bar, free pool table.
The only thing that let the hotel down is that the pool is very outdated, the outside of the hotel needs a repaint (by the pool), there's no snack bar or bar at the pool, and the sunbeds are very old. Still very clean to be fair and adequate for an end of day swim, however not really suitable for half a day relaxing due to the lack of facilities.
Halong was a nice town, however when we went at the start of September it was a ghost town almost, which meant our hotel was also extremely quiet.
The area felt pretty safe, we didn't have any hassle apart from booking a taxi back to Hanoi airport. The hotel charges $80 each way, but it's safe and reliable. We found one for $30 on the way back to save money, but it definitely wasn't reliable or a safe journey back, so I would recommend the hotel service any day.
