What type of clientele are you looking to get? (i.e. budget friendly, mid-tier, high earners).
As a guest(I fall somewhere between mid-mid plus), I would not pick your space. I personally don't like airbnb's who try to squeeze in as many guests as possible. You have 2 rooms, 4 people should be your max. Respectfully, it looks like the furniture is older and used. The carpet is a big minus. I wouldn't feel like I'm on vacation with the current state of your space. My opinion would be that this is a budget rental and $140 seems high per night. There is definitely a market for budget rentals but you will always be chasing your competition's lower rates. Unless your location is 5 Star, I would think about renovating.
Get professional photography. This is a must.
