@Kay1784 The #1 thing you must do is make sure you have the approval of your landlord that you can list the apt on any short term rental site. And, if this is a condo, you need to know if the condo association allow STRs.
On your questions, it’s difficult to answer because there are too many variables—location of rental, condition or ambience of apt, number of bedrooms/bathrooms, amenities provided, reviews from previous guests, etc. The best you can do is a search at airbnb.com to compare your rental with similar renters in your location.
Good luck to you.
