I stayed at FLC Ha Long Bay for 3 nights in November 2019. I found the location stunning - you can't beat an elevated view of Ha Long Bay. The hotel is brand new, only 2 years old. There are many parts that are very nice...the appearance from the outside, the lobby, etc. However, there are some things that aren't ideal - it's a cheap flooring in the rooms, there are some craftsmanship issues that you notice - like too much grout in the shower, tiles that aren't quite square, flooring that leaves a small gap to the wall. There are also just some things designed poorly - like a slippery tile in the indoor pool area. And the pool is next to the gym - meaning that because the pool area is heated and moist (to keep swimmers warm), the same warm moist air is in the gym - so the gym is 24C-25C or 75F/77F while also being humid. This makes the floor slippery and a workout very uncomfortable because it's so humid. There's also just some sloppiness with the processes (not the staff, they're very good). For instance, checking out took a while because there is only one credit card reader - seems like something that should be fixed.
Alex, the assistant GM I think, is excellent. He was super helpful at all times, very friendly, and relatable. I highly recommend him.
The golf course is pretty awesome too. Immaculately kept, every divot is repaired by hand by the caddies. Every tufts of grass is picked up. I've never seen such well kept fairways.
