Me and even the professional agencies are now posting their summerhouses in Scandinavia through AirBnB. The market for renting summerhouses in Scandinavia is big business and has existed for at least 100 years and professional online portals has existed for several decades. AirBnB is no longer just a portal connecting hosts with an airbed and breakfast to potential guests, but still AirBnB needs to implement some of the learnings from the above mentions players to be the future portal covering this market (my best guess is that this market consists of way over 100.000 houses only in Scandinavia). We mostly rent houses by the week and we charge for power, water and heating consumption. Therefore, AirBnB, please focus on developing tools to make AirBnB better, concerning these requirements. For me it seems very simple:
1. Extend your feature to add prices per week to enable prices "from and to" to not only Monday to Sunday, but from and to any weekday. In the summerhouse marked the day guests come and leave is mostly on Saturdays, but could also be on other weekdays.
2. Instead of just requesting money, please make a dedicated feature to charge for power, water and heating.
if above is implemented in the AirBnB-portal, I am sure that AirBnB will conquer the entire market for summerhouse renting in the Nordic contries and probably also in the rest of the world.
