I have a vacation rental in Santa Fe, NM. I have 5's for all categories except Value and Location, which are almost always 4.8.
The "Value" rating I get because my property is pricey. The location: really? The listing in several spots says it's 16 minutes from the center of town. Also, it has vast mountain views, which simply don't exist closer to town. I accept it.
An interesting note: when we first started our vacation rental, our prices were about 1/3 of what they are now because we were brand new, had zero reviews, and needed guests. Guess what? I had several lower "Value" ratings. Everything else was "5 stars". I guess people tend to think they've spent too much, and that's okay. If guests say they got a great value--maybe you aren't charging enough. I am not about to lower my price .
