Basically, you are running a B&B since you do "provide services" to your tenants. (Or you would, if you actually had a tenant in 2017). Overall this would be claimed on SCH C as business income, the same as a hotel would. However, since you have no rental income for 2017, it makes no sense to claim squat on the 2017 return, since your expenses can only be deducted from the business income (which you do not have).
You "may" need to check with any authority within your local jurisdiction too, to ensure you're meeting the requirements (if any) that may be imposed on what is classified as "short term rentals". I know in my city if within the city limits, the city imposes a $3 "bed tax" that I have to pay to the city for each night a bed is occupied by a paying customer. Thankfully, I'm not within the city limits.
