I would highly recommend Mia Resort for those looking for a beautiful, romantic getaway.
This review pertains to a Garden View King Size room
The entire place has beautiful views of the bay. Nothing much was available at the time of our booking, so we had to choose a "garden view" room. Surprisingly, the view over the tops of the trees was ocean-facing. All of the rooms seem to be, although they are built into a hillside and, of the two garden-view layers, there is a definite advantage to being on the top tier.
The room itself was sparkling clean and much more beautiful than in the pictures. The door "wall" opens up completely, and you can just lay in bed and enjoy the beautiful view and sounds of the ocean. There are standard room amenities at standard prices.
You have access to the three restaurants, and each has absolutely gorgeous views. I would recommend picking a table you want for sunset and asking to reserve it the day before. We were pleased that the prices, though high for Vietnam, were not "stranglehold" resort prices-- more like standard US restaurants. ($6-10 drinks, $15-30 dinners). The food was fantastic!
We booked in rainy season. It did rain most of the time that we were there, but it wasn't bad at all. There are a lot of beautiful views with roof-cover.
We did not do any activities, so I can't attest to the quality. We did get some massages, and that was a great experience.
All in all, great stay. Book it!
