I stayed at the Thang Long Hotel
for a week when I was in Ho Chi Mimnh several years back. Very convenient location, clean, friendly staff. Breakfast was included in the price. about 11 years ago
if you want to pre book thats cool there is hundreds of places but if you go to the area of pham nu lao its the backpackr tourist district and a block from the maarkets and it is the city, as in its in district 1 which is the main city area you will find heaps of hotels and they are cheap, if you want a pretty secure room nothing is absolute you pay around 14 a night with breakfast, but its clean has a fan or aircon own bath room and a decent bed, i highly recommend you find a hotel and see you they are friendly because if you are friendly to them they will return the favour and thats important in a hotel in a tourist district.
madame cu'c is good, i lived in saigon for 6 months but moved out of my apartment a week before flying home and stayed there for a few nights, they were fantastic. almost 11 years ago
