I was informed there was works at the house in the morning before checking in. There was strong smell of chemicals when I opened the main door. If I closed the room door and opened the window, it was fine. However, the carpet and corners looked uncleaned. The point made me send my request for refund was the full litter bin in the allocated room.
Please note there are more than one room shown in the twenty five pictures of the house. Do check which room will be allocated for you. The allocated room for me was in the last few photos, not the first bright one. That one was locked. Mine has a window, not as dark as the photos indicate, but decorations are different, besides the mentioned.
