Helium is correct. The melting point is less than one degree Cover absolute zero. Yes Cs being an alkali metal reacts violently with water. It melts at a temperature of 38.4 C (83.2 F); really just a warm day.
On additional investigation it would appear that Fbone's suggestion of Francium as a liquid element may be valid, it being a rare element with only radioactive isotopes there is not a precise value for the melting point. I was not considering any of the unstable elements so it was not on my list.
Interesting piece of trivia. There are two elements that are named after the country of France, Francium and one the elements that are liquid at normal temperatures that has not been named yet. Not sure what if any significance there is to that.
