Many thanks for your message and feedback. Hopefully I can clarify the above point mentioned. Like explained in our exchange this website does not offer flexibility when 'advertising' for the nightly price and uses the lowest fare based on the lower rate in any given point in the year, i.e. in the middle of the winter on a nightly rate. There is a minimum stay at the villa as well as a weekend price. This clearly was the case for the weekend in May which you've booked. The price was communicated to you prior to the booking and on that basis you have booked the villa. There has been no hidden / additional costs from the ones you agreed upon when booking the villa. As explained numerously Air bnb charges a commission, and keeps the security deposit. This is all explained in the quote and then invoice you receive when confirming the booking. There is always an option to cancel a booking if you disagree with the offer.
Hope this answer your question. We always try to accommodate for all types of holiday, clients and formats - for instance I have allowed to accommodate 2 extra people in your parties understanding the purpose of your trip, i.e a hen weekend do.
We've only had very good feedbacks so far and hopefully people do enjoy coming to the villa.
I hope that clarifies the above.
