First of all, a Ferienwohnung is an appartment for rent. And as it happens, I have a new project, where I try to market this appartment online. You can check out the site of the apartment for rent here, if you are curious.
I was looking for a booking system to use for this. And just as I was about to make the decision to write one myself, I found this service called supersaas. They offer a good service – unfortunately, it will set me back a few euros, but it’s better than doing it myself. 
So, I can recommend supersaas. Check it out, if you need something similiar.
