Cleaning and other rules

Twice a month there is a service of house cleaning:

Am I obliged to include cleaning in the price?

As it is a private space for the exclusive use of residents, as is customary in these situations, cleaning can be left to the responsibility of guests.

And how is the cleaning of shared bathrooms?

It would be impossible to guarantee cleaning every time a guest uses a bathroom. The responsibility for sanitizing afterwards, and even before each use, is the responsibility of the guests. The local accommodation is obliged to leave cleaning and disinfection products so that guests can manage these tasks.

Is it necessary to guarantee the change of bed linen and towels?

As long as they have a washing machine, the task of managing clothes can be left to guests as usual.

In this sense, it can be agreed that the guest himself brings his own change of clothes or leaves two changes from the AL whose cleaning is then managed by the guest himself.
