Good hotels, from what I thought was a reliable source.
Bi Saigon in HCMC.
Helpful people, good sized rooms.
BUT Run down and dirty. That is my wifes view.
Angella in Nha Trang.
Good bet we paid 28 US a night including breakfast. Just off back packer zone and 7 mins walk to beach. Best bet Louisiana brew house on the beach for chilling out. You can use their pool as well for the price of 25 000VND
More to follow. Oh yes train Journey an adventure, the Hotel Bi Saigon whacked us for tickets, but frankly small beer. Bunks small even in class one if your biggish. Great fun, but difficult to find food , so go prepared ! More info to follow
