You'll need blower fans to dry out the floor and walls. Dehumidifiers would also be a help.

Your landlord should be concerned about mold and working on the repairs. The way remediation companies do it is that they drill 1 inch holes along the base of the wall to allow humidity to escape. The fans will provide circulation to dry out the walls. If the walls are still humid after about 3 days, then those portions of the walls are ripped out and replaced.

There are professional companies that specialize in flood remediation. These are good, particularly if you have renter's insurance. Much of this can be costly if done right.

If you do employ blower fans and dehumidifiers, one surprise is the cost of electricity the next month. Humidity is the enemy. You want to dry out everything as quickly as possible to avoid making yourself sick from mold.
