My 60m2 big flat is nice and cosy. For you I have a 20m2 big sleeping room with a double bed. I might stay in the living room, if you are lucky I am out of town and you have the whole apartment for yourself.
In my flat there is also a bathroom with a big tub (with whirlpool function), an extra toilet and a nice kitchen.
I have a wahing machine you can use and a dishwasher aswell.
