Hello @Adalina22
If you are worried about who you are sharing your apartment with, which is quite understandable, I just wanted to let you know that Airbnb gives you the option of selecting all female guests if this makes you more comfortable IF you are present and sharing amenities with your guest. Have a read of the link below if you are interested in specifying this on your listing:

But you're right, there isn't much information on a potential guest so to avoid any bad surprises, I wouldn't allow Instant booking and then communicate with your potential guest via the message system to get to know them a little.
Happy hosting
Joëlle
