@Baigal0 you can protect yourself by vetting the guests carefully but no one can guarantee that it is safe. Will you be staying in the apartment too? I you are, you can choose to only host female guests but you have to disclose it. If you are away when you receive a booking you can lock all your valuable items in one place. Don't turn IB on, only allow guests with verified goverment ID and several good reviews book your place and you should be good to go. Don't forget to write down the house rules. Be friendly and helpful with guests but only to a certain extent, do not let them feel like they can do whatever they want because you are scared of a bad review or unhappy guest.
