no.

extra beds.
it is a studio apartment, so it by default best fits a single person. 2 is still a comfortable number of people in the flat, but in case of a family of 3, there is also enough room and linen/towels for the third person.
there are two sleeping areas; a double bed and a pull-out sofa bed /converts into a double bed, very easy to use and comfortable/.

pets and smoking.
sorry, no pets or smoking are allowed in emmi.
in slovenia, smoking in closed areas /cafés, bars, public buildings, apartments .../ is forbidden by law.
