Hello @Mattias42
One thing to consider maybe would be to provide a floor plan with dimensions of rooms that you could put in your pictures. Your place provides 30m2 of space for 4 people so maybe your guests are expecting a bigger space?
Your listing says 1 bedroom just under the general description but a bedroom normally has a door and even though you clearly show an attic with two mattresses on the floor, guests might mark you down on this for accuracy? There is an option in the bedroom section to put mattress on the floor - have you ticked this box?
Very difficult to say without staying ourselves but as @Helen3 suggests, the best way is to ask your guests via message
All the best
