The tiles on the ground floor were left in a terrible state after the renovation. We tried cleaning with a mild acid product, but without much improvement. We asked Michele if he could help and he told us we needed a specialist floor cleaner.
We cleared as much from the ground floor as we could before leaving in February. Michele and one of his guys moved the heavier furniture.
Michele sent us this video of the state of play with one more protective coat to apply. Looking so much better.
