Well. the bombshell last year was that the website we relied on for most of our custom was taken over by an American company (homeaway), who promptly put up their listing prices more than 500%.
Due to the short season, and rentals achievable, it was clear that this meant we had to decline to pay their fees and look elsewhere.
We are experimenting with booking.com but their system, which was originally designed for hotel rooms, is very cumbersome, and to me often completely inscrutable. Also, we have to be bound by their terms and conditions which are far less flexible and to my mind far more open to exploitation by renters who don't arrive and don't therefore pay.
We have three bookings for high season next year, but whether they will actually translate into euros remains to be seen.
Anyone here who wants to enquire about the odd weekend or any other period before July or after August, please email me.
