Where to get laundry done this weekend during Tet?

We are only in town for a few days before traveling north with a tour group. Totally out of clean clothes and need laundry done or a place to wash and dry it ourselves by Tuesday. Everything seems to be closed except exhorbitant per-piece laundry service from our hotel, Asian Ruby Select.

Near my home have one. Cross hồ ngọc cần and dân tộc,  tân phú district.
