Hi, there are a number of Liberty Hotels in HCMC, assuming you are at the one on Le Thanh Ton St, almost next to the Ben Thanh market, turn right from the hotel and first left is Nguyen Trun Truc, turn left here and about 100 - 150 metres up on the left there is/was a laundry down the side of a building. It has/had a sign out the front with a bell. This information based on 1 years ago.
