Water mineral water. When we ask to the staff, they just answer our water tap using filter so you can use it direct to drink. But in a few minutes, he came to brought 2 bottles mineral water maybe 200ml (smallest bottle) but we reject it. One good thing from this place, if we came earlier and we are not allowed to do early check in, we could keep our stuffs with additional charge cheaper than we keep in the station. Our first night hotel in stars apartment KLCC much better than this place (cheaper, bigger, clean).
