@Samson36 I just looked at your listing and you're doing everything right. The apartment looks crisp and clean. I am totally in love with that coffee table.
I'm not sure how long you've been up and running but there's so much competition right now it might take time to build a track record but don't settle and don't compromise. If someone tries to "negotiate" a lower fee, or pay outside of the platform, just pass. Saying no is hard, but dealing with demanding difficult guests who mess up a place is harder.
Hosting up to 10 people is as hard way to start (I can legally host 7 but limit my apartment to 4-5 people to reduce wear and tear). So play that by ear and determine if you really want to max out the house while you're getting a feel for hosting.
I tested your listing by choosing random dates and increasing the number of people. Good job charging based on occupancy. There are some people who will book for one person assuming the rate is the same even if they show up with a crowd. I make it clear on my listing that only those on the reservation may enter the apartment without prior permission. And I do charge for each additional person over 2 people. It's a lot of space and still less than a group would have to pay at a hotel.
On the dining room, sometimes people want to "see" themselves in the space. Since you put plates on the table for the photo shoot, why not finish and set the table (place mats, or glassware, etc.). I don't think people expect to see it when they arrive, but it gives the "feel" of being at home.
Over time, I would add lamps or a small chair to the bedrooms (find some at a high end estate sale in your area - you'll get better quality furniture then buying new) Eventually something on the wall (photos, wall hangings, etc.). Doesn't have to be much, but would help give the rooms more character and look less like a "rental." You want to give people the illusion they're staying in someone's home so they'll take better care of it.
But the decorating part is a long term thing. Wait to find pieces you love that work with the space. No rush. Keep this a work in process and then key off of the comments you get from guests.
Overall, it looks like a place I would book if I was in the Houston area. So far, I think you're off to a great start. Welcome to hosting!
