It's around 2.5km from Phong Nha town centre, but they have a free shuttle on check in and out. Place is beautiful, peaceful, you can hear the frog music in the evening and see a sunrise just from your room. Staff is very nice and helps with everything making sure you really enjoy your stay.
I love markets in Vietnam and the one in Hoi An has a totally different vibe. Colorful lanterns, smell of food and variety of souvenirs are everywhere. There are many fresh fruit to try and they even make ice cream of them
