My listing is a private room/private bathroom in my home. Guests share my kitchen with me. There is no reason why hosting can’t be both profitable and enjoyable. Those things aren’t mutually exclusive. I tend to get quite interesting guests, many of whom I chat with over coffee or a bottle of wine, have made new friends from all over the world, so that part is fun, but I certainly wouldn’t host for free.
And I can assure you that no host considers cleaning other people’s hair covered in soap scum out of the shower drain to be something they do for fun.
I can also assure you that I haven’t invested a bunch of money. Everything in my guest room are things I already had- the furniture, the lamps, the pictures on the wall. I made the curtains and throw pillows myself.
However, if you are going to host successsfully, newer decent linens and towels are part of that. Charge enough that you can afford to buy and replace those as needed. They don’t have to be expensive at all- I always buy those things on sale.
You asked for a critique, but are being very defensive and resistant to the responses. Honestly, other hosts here are trying to help you- try to receive it as such. Doesn’t mean you have to take everyone’s advice, just try to be open to suggestions. Advice is offered because we want to see fellow hosts succeed.
No you don’t need new furniture, your furniture is lovely. No, you don’t need to hire a professional photographer. No, you don’t need to repaint (when I put the old house I owned and lived in for twenty years on the market, the real estate agent told me to repaint all the walls white. I had used a lot of paint colors- rust, turquoise, yellow, teal, brownish-grey. No way I was repainting. The first people who came to the open house said, " We love the colors!", put in an offer immediately, and bought it).
But you do need to make the beds so they look clean and unslept in before you take photos (one bed has the bottom of the sheet hanging out all messy) and you might need to purchase a few new sheet sets. Antique and full of character isn’t the same thing as shabby-looking.
