Thanks for your review.
Just let you know that I don't accept pets in this studio, so dog hair would be impossible to find.
That was probably natural fibers from a blanket I just washed what you found on the sofa bed.
Also, let you know that cleanliness is one of my top priorities and of course the studio was perfecty cleaned before your arrival.
So, It's pretty unfair what you said about the global studio cleanliness.
Also, if you would have let me know while you were here I would have been more than glad of providing an extra cleaning service for the sofa bed.
