We got back yesterday. The house smells fusty/of damp and still does this morning. It's not long renovated, and I can see a couple of damp spots on the ceiling from a crack in the rendering that we know about - but they've been there for ages. There's no signs of any other damp/problems.
DH says it's because it's been wet and no one has been here, but that doesn't sound right to me.
Any thoughts?
