We were sorry to hear that Ursula found our apartment not too clean. We try to do a thorough job, but obviously we overlooked something. Apologies for that.
Ursula is correct that the bathroom attached to the master bedroom does sometimes have a bad smell. This is a defect in the plumbing throughout the whole building that happens when the pipes get dry. We wish she had let us know right away, as the problem is easily solved by running water through the floor drain. We could have saved her a few days of unpleasant smells with this simple solution, had she dropped us a note during her stay to let us know.
We are not sure how to understand "not really well looked after". If there were specific concerns about sheets, towels, furniture, or anything else we would have welcomed the chance to fix the problem immediately, had she let us know. In any case, we will do our best in the future to continue to keep our guests as happy as possible!
