I'm disappointed that Adam felt this way. We were very careful to clean up after ourselves with the limited cleaning utensils to hand. As our other reviews reflect, we do our very best to be courteous to our hosts and treat each space with the same respect as our own house. I'm sad that in this case it wasn't perceived this way.
I decided to keep some criticisms about the cleanliness of the flat, such as fake tan stains on the towels provided and a bath plug blocked with other guests hair, private with Adam as I didn't feel these were things that couldn't be easily changed by him before other guests stayed.
We stripped the bed and left the bedding with the towels ready to be laundered. We did our dishes and left them to air dry by the sink. There were no dish towels to hand dry them. Had there been instructions to do anything special before leaving we would have gladly done so, as we have done for many other hosts. We checked out of the apartment in the same condition we found it and I'm left feeling confused as to what else we could have done in this situation.
Further to messaging Adam regarding this he informed us that he did not in fact see the apartment after our checkout with his own eyes and was going on the fact his cleaner had mentioned it had taken longer to clean. Perhaps they thought our air drying dishes were yet to be cleaned, perhaps it was the stained towels or perhaps it could have been the hair in the bath but we have no way of knowing as Adam could not provide us with specifics.
