'Person without bed' Charged Extra??

[martinf]

As a single traveller I am looking at rooms in Krk during my stay there but a bit confused by something in most adds for rooms, can anyone please explain what it means by 'Person without bed'?

Surely when I book a room, I pay for the room regardless if there are 1 or 2 people in the room or am I being charged extra as only 1 person?

Very confused by this.
