Hello @Sam8045
Good news! I made a private search on Airbnb.mx and entered a week in August (had checked that these dates were available on your calendar) and entered 11 guests. You came up on page 2! So that's great.
If your house managers didn't enter any dates and put in a low guest count then this might explain why your place didn't show up. You hava a capacity of 16+ so the algorithm is unlikely to throw up your place if no guest count or a low number of guests is entered in the field as there are thousands of other places to choose from.
Your place is lovely, you have a promotion in place so you just have to be sure that you are competitive in relation to other houses similar to yours.
Wishing you a great season,
Joëlle
