Some of your guests may come from countries where shoes are not worn inside. Wherever we step with these outdoor shoes, will be carried to our homes, and eventually to our carpets, beds, etc. Taking off the shoes inside will significantly increase the quality of the indoor air and reduce any possible allergens. Also, you will save your floors and carpets.
In short-term rentals, things tend to break down easily or go missing. That's why it is smart to prepare for the losses. One of the most efficient ways to do the inventory is to incorporate it into your cleaning routine. Check that nothing is missing, dirty, or broken. Take photos after each cleaning and you will always have stronger proof than just words.
Heat is something that we all experience uniquely, and everyone has their preferences on how warm or cool their living environment should be. Being able to control the indoor temperature and set it for your preference should be every man's right. If guests feel either too hot or too cold in a place, most likely they will never return.
A washing machine can be crucial if you plan to host guests for a longer period. When staying for over one week, most of us will run out of clean clothes and need to do the laundry. Nobody wants to do their laundry outside, so ideally you would offer the washing machine inside your apartment or, at least, in the same building with private access for your guest.
