@Mijo0 If you published your listing within the last 24 hours, you may need to wait a bit since it takes that long for new listings to appear in search results.
When you search for your listing, be sure you enter dates that your listing is availble taking into account any minimum night requirements (i.e. if you have a 2 night minimum be sure your check and check out dates are consistent with this requirement), enter the number of guests you can accommodate, enter amenities your listing offers. Do not do a general search just by property type...given the number of Airbnb listings in Croatia, you are likely not to find your listing. Any time you see 300+ listings you will need to add more guest preferences (filters) to find your listing.
If you still cannot find your listing, I'd be happy to look for you!
