@Sarah2164Wow! What a gorgeous space!
The description of the listing is great - it really provides guests with everything they need to know. One thing I've learned from reading through the posts of the wise people here in the Community Centre, is that (unfortunately) many guests don't read through the listing. Maybe adding descriptions/pertinent information in your photo captions would help entice people to book...
I did a search of Caba Beach, and your listing shows up on the 2nd page, which might be one part of the problem. Also, while I think your price looks entirely reasonable, it seems to suffer when compared to two other whole-home listings that sleep 12, priced at 357, and a condo with ocean view sleeping 10, priced at 348. I'm sure you've priced in accordance with your amenities, but as a "casual looker", I mightn't actually click on your listing so see how gorgeous it is, if I were just doing a straight price comparison. As Beth suggested, above, you may find dropping your price might give you a boost, when your listing is new.
All the best!
*Editing to say that the prices as I've listed them above have been converted into CAD from AUD, so will be different from what you've set. (Just in case you were freaked out by the prices as I've listed them being lower than what you've set.)
