How to figure out reasonable rental rate

Hi everyone! I work in healthcare. In healthcare there is a lot of temp workers who travel for work. I just bought a house that has a detached in law suite. It’s basically a guest house. It has utilities, internet, is fully furnished, full shower, towels, laundry room, kitchen, dishes, two TV’s and part of the furnishing besides a full bedroom, it has a dining table, and a pull out couch for a second bed. I would say it’s likely about 800 sq feet.

Location: NW Ohio

Drawbacks are there is no access to the thermostat, because the main house thermostat controls the guest house temperature, though I do have a space heater in there for warmth, as we like our house pretty cool.

With all of the amenities that I am offering that would be included, what should I charge above the typical apartment in my area? R/t being furnished, utilities included, access to streaming apps, and internet?

Typical one bedroom rentals here are $750/month
