How many views is Airbnb showing for your listing? I don’t know how reliable or meaningful those metrics are, though. Something I wonder if they are randomly generated by Airbnb. Though I do seem to get booking at peak view times.
Also, you mentioned you only got 3 bookings? But what about inquiries?
Parenthetically, I agree with @K9KarmaCasa that reworking your photos would not hurt. And definitely include photos of everything relevant, including the bathroom and kitchen. It used to be the case that Airbnb provided hosts with free photos, but I don’t know if that is the case, and it’s location-dependent, anyway.
Also, you definitely want to get wifi as @SandyToes mentioned. That’s crucial these days. I’d also get a hair dryer. It won’t change whether people book or not, but it costs next to nothing, and people do use it.
