In January 2018 I spent 2 or 3 days in Phu Quoc. It was lots of fun! I recorded this video to remember my trip, and also bring you along on the adventure!
I recommend traveling to Phú Quốc if you get the chance! While I don't recommend living there (I'd imagine it would get boring after a while for most people), it's well worth a weekend trip from Saigon or southern Vietnam when big city life has you feeling burnt out.
