Lovely photos, cute dogs, and your dates are good, some put them to start on the 31st Dec or end on the 1st Jan, but you haven’t done that so that’s great!
Remove the word Californian from the bungalow bit, it may add slight confusion about your location.
The wording of you ad is good too, I would add the minimum dog walk you want to take place each day, but it’s great you seem flexible in the way you have worded it, so just tweak it for your own benefit, so you know they will definitely get walked!
Also, mention the distance/minutes to the nearest food shop etc.
I can understand you saying no visitors with it being New Year (ie party-time for some), but after you fill this sit, perhaps remove that line and play it by ear based on who you have apply, but don’t say you’re open to guests in your profile, just say nothing, because it puts a negative in someones mind about you, even though they may not have any intention to have guests visit (we’ve been sitting for 1.5yrs full time and haven’t had a single guest at any property as yet, we’d rather meet up with people in a cafe or restaurant), it’s just with it being a negative line, when you have a great profile overall, very positive, light hearted wording, so there’s no need to put a negative in. If someone applies and asks, you can simply say no you’d prefer not to have guests at that point, that’s totally fine, it’s your place, your rules.
With your 8 favourites - Sitters can’t reach out to owners unless they apply for dates, and if they are already booked for New Year, they can’t reach out to you at all. Whereas owners CAN reach out to sitters. So the people who favourite’d may not be able to reach out to you, so I would pop them a message saying you had noticed they favourited your place, and ask if they are interested, or invite them to sit, but you have 8 so I’d just message them all at this stage, given you are new, rather than inviting them and see what people say when they respond. That way they can then respond to you, because it may well be that one of those sitters may suit you perfectly for your future sit dates.
But it’s a lovely profile and great pics. Good luck
