In the case of recurring cleaning, as well as one-off cleaning, it is best to be present at the first appointment to welcome your cleaner in order to show them the premises, explain your expectations and show them where you store your equipment.
You will be able to explain to them your priorities and specifications and you can take advantage of this opportunity to hand over your keys if you do not wish to be present at each appointment.
Our cleaners are used to working in private homes in the owner's absence. You can therefore entrust them with your keys with complete peace of mind.
In case of absence, you can tell them where to collect your keys and where to leave them when they leave (with a neighbour for example); or you can ask them to keep them with them for the next appointment!
