@Rajan2 Yes, you have to have a thick skin to put yourself out there for a critique, but lots of hosts do and I think it can be quite helpful.
In your case, there is really little to fault- your place is lovely and your reviews are fantastic, so you're obviously doing the right things. The couple reviews that mentioned that they didn't think it was good value, or that it wasn't as close as you made it sound to attractions are obvious outliers- some people just need to find something to complain about, but your responses are totally professional.
The only things I'd suggest are:
Edit your listing description a bit so it sounds a bit more personal, rather than a real estate ad. I've read a lot of posts here on the forum where hosts had partiers who destroyed the place, and when I read the listing description, it was quite impersonal. Just a line like "My wife and I had a great deal of fun putting the place together in a way that we feel is both comfortable and elegant" sort of thing just gives a personal touch and conveys that it is a home that you've put a lot of effort into creating and care about. As you live on the property, that effectively kiboshes partiers and sneaking in extra guest types, and while you mention that you live on the property farther down under host interaction, many guests just don't bother to thoroughly read all the info so I'd work a line into the description, as well.
I find many of your photos washed out- maybe you could play with the contrast a bit. Also some of the photos I find redundant- you can see the whole bed area in the first photo, so the close-up and the one with the plant are unnecessary. Maybe replace with different angle shot. Same for the front door shots- just one is sufficient. And too many photos of local attractions for my taste, but maybe that's what guests coming to your area like to see, so take that with a grain of salt.
All in all, great listing with happy, appreciative guests. Congrats.
