If it's the one down in the corner with the stairs (beige) immediatly to the left as you go through the front door, she was the same with us; however we did explain all about them, what causes them and what to expect (i.e. they will come back) and did remove them using Ultrapak Renovate spray/ aggitate/rinse with hand tool and towel after. She seemed to be obsessed with the draft marks. She was happy when we left. Did she go round and check them ALL? She did with us.
