This is just crazy. The room was completely clean and the sheets had just been returned from the laundry. Nothing was covered in a scummy dust as I had personally overseen it that morning after it had been cleaned -with all surfaces and brochures wiped and disinfected. The smudges on the shower may have been because it had been treated with lime scale remover. The sink had been bleaches and similarly may have had lime scale remover.
The smell is something to do with the apartment block over all which happens occasionally.
only the american guests ever have problems with the internet access which may say something ?
