Not every floor has a sink or a toilet so be prepared to walk up or down a flight of stairs for access. Some toilets don't have sinks so you'll need to take the stairs for that as well. Best thing I did was take a pair of flip flops and a light bathrobe.
Despite the size of the room, there was a fridge, microwave, coffee maker (with coffee!), iron, AC/heater and one more item I can't remember because I didn't use it...
