If you are interested in the question of how much space a person needs for a comfortable stay, the designers from the Swedish company Alvhem Mäkleri & Interiör will answer you simply - 26 sq.m. 
What is really problematic insuch small rooms, so it is the introduction of a full and comfortable bed. After all, the bed seems out of place here, and it is not so comfortable to sleep on the sofa. 
The golden rule came to the aid of the designers.means, which often saves us, if we can not decide. In the specific case, the bed was hidden as it were, which the designer achieved by correctly placing color accents. They became a sofa with colored pillows and a bright picture on the wall above it. 
In order not to clutter the space, the usual fridge was replaced by two freezers installed under the counter. 
We must not forget about the functionality. A wide window sill will become an additional storage place for accessories, a shelf above the bed - an element for books, and a built-in wardrobe - for clothes.
