The apartment is a converted half basement old storage place of the apartment building upstairs. It is located close to the gas burner that heats up the apartments upstairs. As such during our winter stay, the hallway smelled like gasoline constantly. Also by construction safety standards the door to the apartment, with it being so close to the gas burner, should be fire-proof and there should be an emergency exit at the apartment hallway on the side of the apartment, not on the other side of the hallway. There was no exhaust hood/window in the bathroom and when you take a shower all of the moisture stays trapped inside the room. The kitchen hood has a hose that doesn't lead to the outside of the apartment, so after cooking all of the smells and vapours get trapped inside the room. We found hair inside the drawers and on the sheets and as such we used our own sheets. Despite all that the host responded immediately to our requests and a mixup with the checkout time that was our fault.
