So if your living in tourist town Hoi An wtf you in this group for we don't care about your life in Vietnam and you had nothing to offer the OP but brag how easy it was in Nam pfft.
All depends on many factors, impossible question to answer because we are all individuals and require different needs and life style's, your probably better off coming over and spending time here then you will probably then have a fair idea what you're going to need.
