You can get all sorts of printed material at vistaprint. Free business cards and you use their artwork or upload something you've designed. I do a (one page, two sided) mini-newsletter and annual report using their flyer. I don't actually get them printed, I deliver them electronically, but it's great to have access to their templates and artwork.
Create your own web site. I use webs.com for both of my properties. On the site you can use a URL straight to your airbnb listing for those visitors who want to make a reservation. Webs.com is free and again, there are a ton of apps that are both helpful and free.
Think about who in the community have out of town visitors and solicit their business. My background is nonprofit, so any arts organization that has visiting artists, I put together an email database and send them an email blast about once every 3 months. I also assembled a database of contacts at nearby hospitals. Finally, I put together an email list of special event/wedding planners. All of these folks get email blasts about every 3 months. I include any specials I'm running, recent improvements/added amenities, and other news.
Keep in touch with former guests, put together an email database and email them occasionally. They may never come to your location again, but they might have friends, co-workers, etc. that will.
I have a FB page but have not had a ton of luck with it. I use it as a way to keep in touch w/ people, link articles about Pittsburgh and upcoming local events, etc.
Finally, develop a network of other hosts in your area and exchange referrals. About 15% of my business last year came from referrals from another host.
