We only list on Airbnb so we don't need any channel managers or clever software as Airbnb does all that for us. Their user interface is good once you get used to it and tells you everything you need to know.
It sounds like you will be quite hands off with your place. As such you will need a co-host to organise/clean the place, welcome guests etc. Do not listen to co hosts who think they can manage from a different country (or even state). You need one local to the listing so they can sort out problems if they happen.
Depending on where you are some laundries will supply linen as well as washing/ironing it.
Just be careful as by the time Airbnb takes its cut (about 15% of what the guest pays, a co host takes their 10-20% depending on if they are cleaning or not and you pay the utilities etc then there may not be much money left for you. It depends if you will charge $500 a night or $50!
Finally, before you start, just make sure Airbnb is allowed in your town and you have the proper insurances in place.
Good luck
