I stayed a week at Vung Bau and really enjoyed my stay, minus a few problems.
I was contacted by email regarding pickup, without problems. Greeted upon arrival by Chi, with a drink and taken immediately to my room. A small garden view room, spotlessly clean. further away from the restaurant but also away from noise of the dogs, chickens and roosters. Great water pressure, hot water as well! Wifi a little spotty and electricity out in my room one night, was resolved quickly.
Breakfast included, list of made to order then as the hotel filled a buffet. I was limited to what could eat as most selection has meat in the dishes. most of the food was good but the prices higher than other areas. also found the service sporadic and inconsistent. One day not receiving my drink because server was playing pool, another day they simply forgot my drink.
The managers Loum and Chi are so kind and are constantly trying to ensure your stay is perfect but language and culture differences cause a few issues with the other restaurant staff.
The good outweighed the few mishaps...I enjoyed the simple, quiet, isolated beach and would gladly return.
