There are no secrets or catches to staying with Andreas and Nam. They were very helpful in providing maps and explaining general transportation tips and tourist trips. They greeted us warmly and with hot tea and were very good about communication when necessary. The room was perfect for two guests and located just across the street from a main source of transportation, the M Tram system, leading to the S BAUGN AND U BAUGN. Highly recommend staying with them for comfort and a very fair price
