I'm with Gerry. You have good photos, but it does look like they were taken at night.
I did the same thing when I first listed. I took my pictures at night. A couple weeks later I went back and took new pictures, this time in the daytime and the blinds open. The pictures came out a lot brighter and inviting. The best day to take pictures is when it's cloudy out. Direct sun outside will be too bright.
And I'm still a new host, so take my advice with a grain of salt, but I think for most people, price is king. When I go for a long stretch without any bookings, I lower my price a few dollars. And then if I go for a few more days without bookings, I lower it again a few dollars. When bookings start coming in, then I raise my prices back up, and if even more bookings come in, the prices go up yet again.
