Under those conditions for pressure and temperature, water can only exist as liquid.

Take a look at water's phase diagram

Normal atmospheric pressure and room temperature correspond to a pressure of 1 atm and a temperature of #"20-25"^@"C"#. Let's use the 1-atm pressure as a reference value, since it's highlighted on the diagram with a dash line.

Notice that, at 1 atm, water can exist as a solid only at temperatures below #0^@"C"#. Likewise, it can only exist as a gas at temperatures that exceed #100^@"C"#.

At this pressure and at any temperature higher then #0^@"C"# and lower than #100^@"C"#, water can only be a liquid.
